In a masm program I have to calculate an average grade of 4 tests, the array values are already declared so no inputs are needed. How do I do that without needing a loop since I’m not allowed to
[tex] \bf \red {Answer}[/tex]
If you're not allowed to use a loop, one way to calculate the average grade of 4 tests is to add up all the values in the array and then divide by 4. Here's an example MASM program that does this:
```
.586
.model flat,stdcall
.stack 4096
ExitProcess PROTO,dwExitCode:DWORD
.data
tests DWORD 80, 90, 85, 95
numTests DWORD 4
average DWORD ?
.code
main PROC
; Calculate the sum of all test scores
mov eax, 0
add eax, tests[0]
add eax, tests[4]
add eax, tests[8]
add eax, tests[12]
; Divide sum by 4 to get average
mov ebx, numTests
cdq
idiv ebx
mov average, eax
; Display the average
mov eax, average
call DumpRegs ; Replace with your own code to display the average
; Exit the program
INVOKE ExitProcess,0
main ENDP
END main
```
The program declares an array `tests` with 4 values, a variable `numTests` with the number of tests (4), and a variable `average` to store the calculated average grade. It then calculates the sum of all test scores by adding up the values in the array using the `add` instruction. It divides the sum by 4 to get the average using the `idiv` instruction, which divides the double-word in `edx:eax` by the value in `ebx`, storing the quotient in `eax` and the remainder in `edx`. It stores the calculated average in the `average` variable and displays it using `DumpRegs`. Finally, it exits the program using the `ExitProcess` function.
Note that this program assumes that the array `tests` contains exactly 4 values. If you have a different number of values or if the number of values can vary, you will need to modify the program accordingly.

Which of the following are easy/difficult to handle in Virtual-Circuit and Datagram subnets, and why?
i) Router memory space
ii)Quality-of-service
iii) Congestion control
iv) Address parsing time
Quality-of-service and Congestion control are easy to handle in Virtual-Circuit.
Router memory space and Address parsing time are easy to handle in Datagram subnets.
Why is Router memory space difficult to handle in Virtual-Circuit?i) Router memory space:
In virtual-circuit subnets, routers need to maintain the connection state information for the duration of the virtual circuit. This information can take up a significant amount of memory space, which may become a problem if a large number of virtual circuits are present.
On the other hand, in datagram subnets, routers do not need to maintain connection state information, so memory space is not as much of an issue.
ii) Quality-of-service:
Virtual-circuit subnets are generally better suited for providing quality-of-service guarantees, such as guaranteed bandwidth, low latency, and minimal packet loss. This is because virtual circuits are established beforehand, and the network can reserve resources for the duration of the connection. Datagram subnets, on the other hand, do not provide such guarantees, as packets are forwarded on a best-effort basis.
iii) Congestion control:
Virtual-circuit subnets typically have better congestion control mechanisms, as they can react quickly to changing network conditions by adjusting the routing tables and resource allocations. Datagram subnets may have a more difficult time with congestion control, as they rely on packet-level mechanisms, such as packet dropping, to regulate network traffic.
iv) Address parsing time:
In general, address parsing time is not significantly affected by the choice of subnet type, as address parsing is typically done at the packet level, rather than at the virtual-circuit level.
However, it is worth noting that virtual-circuit subnets may have slightly higher parsing overhead, as they need to maintain connection state information for each virtual circuit.

1. Write a Java application that:
a. asks the user for the daily sales for each day of a week using a repetition loop and calculates its total.
b. calculates the average daily sales for the week
c. displays the total and average sales for the week.
Each of the three components of the program should be handled by a different method.
Here is a Java application that asks the user for the daily sales for each day of a week using a repetition loop and calculates its total, calculates the average daily sales for the week, and displays the total and average sales for the week.
The Programimport java.util.Scanner;
public class WeeklySales {
public static void main(String[] args) {
double[] sales = getDailySales();
double totalSales = calculateTotalSales(sales);
double averageSales = calculateAverageSales(sales);

for (int i = 0; i < 7; i++) {
System.out.print("Enter the daily sales for day " + (i+1) + ": ");
sales[i] = scanner.nextDouble();
}
scanner.close();
return sales;
}
public static double calculateTotalSales(double[] sales) {
double totalSales = 0;
for (int i = 0; i < sales.length; i++) {
totalSales += sales[i];

public static void displaySales(double totalSales, double averageSales) {
System.out.println("Total sales for the week: " + totalSales);
System.out.println("Average daily sales for the week: " + averageSales);
}
}
The getDailySales() method asks the user for the daily sales for each day of the week using a for loop and stores them in an array of doubles. It returns the array.
The calculateTotalSales(double[] sales) method calculates the total sales for the week by adding up all the daily sales in the array. It returns the total sales as a double.
The calculateAverageSales(double[] sales) method calculates the average daily sales for the week by dividing the total sales by the number of days (i.e., the length of the array). It returns the average sales as a double.
The displaySales(double totalSales, double averageSales) method displays the total and average sales for the week to the user using the println() method.

State of Indiana v. IBM is an example of a lengthy and expensive lawsuit that arose out of a failed software development project. In 2004, Indiana’s new governor, Mitch Daniels, announced that his state’s welfare system was “broken” and “plagued by high error rates, fraud, wasted dollars and poor conditions for its employees, and very poor service to its clients.”
In 2006, the state of Indiana and IBM entered into a 10-year and $1.3 billion Master Services Agreement (MSA) to update the state’s welfare system. The SDA required the establishment of call centers and remote electronic access for welfare applications. A paperless documentation system would reduce fraud. Indiana would benefit from the cost-savings in hiring fewer caseworkers if welfare applicants could apply online.
The IBM/Indiana MSA was extremely complex, containing more than 160 pages and extensive attachments, which included ten exhibits, twenty-four schedules and ten appendices. The parties agreed to a ten-year MSA, but Indiana terminated the agreement less than three years into the SDA, declaring that IBM was in breach. In its twelve-county pilot implementation, Indiana documented several problems early on, such as call center miscues, the delayed processing of applications and multiple problems with processing applications for the redetermination of welfare benefits.
Both parties filed suit against each other for breach of contract. Indiana charged that IBM’s product was slow, incorrectly imaged key documents, missed scheduling benchmarks and failed to satisfy Indiana’s policy objectives. IBM defended against these claims, charging that Indiana had created delays by continually changing specifications. IBM also invoked a commercial impracticability defense based upon the large number of new claims for welfare that flooded the system in the wake of the 2008 economic meltdown.
The Indiana Supreme Court found that IBM had materially breached its contract with the state. IBM, however, had negotiated millions of dollars in early termination fees that the state had to pay. The Indiana Supreme Court upheld the lower courts’ awarding of $40 million in assignment fees and $9,510,795 in equipment fees to IBM. The trial court’s award of $2,570,621 in early termination damage payments and $10,632,333 in prejudgment interest to IBM was reversed and the case was remanded to determine both parties’ damages.
This case illustrates the need for careful negotiation by attorneys to protect their clients if the contract is terminated and to clearly specify rights and remedies in the event of breach. Computer companies must be realistic as to what projects they can successfully complete and deliver, while also protecting themselves in the negotiation stage against foreseeable hazards, such as unclear benchmark specifications and excessive change order.

Please add references
The Indiana v. IBM case highlights the importance of careful management of software development contracts to avoid costly legal disputes.
What is the software development about?To better manage these types of contracts, there are several improvements that can be made:
Clearly define the scope and objectives of the project: In this case, the parties agreed on a complex 160-page contract with extensive attachments that contained numerous exhibits, schedules, and appendices. However, the contract did not clearly define the scope and objectives of the project, which led to disagreements about what was expected from both parties.
Set realistic deadlines and benchmarks: The project timelines and benchmarks must be set realistically based on the complexity of the project. In this case, Indiana accused IBM of missing scheduling benchmarks and having slow delivery, while IBM accused Indiana of creating delays by continually changing specifications.
Establish clear communication channels: It is important to establish clear communication channels to facilitate collaboration between parties. In this case, there were several problems with call center miscues and the delayed processing of applications, indicating a breakdown in communication channels between Indiana and IBM.
Anticipate potential issues and include dispute resolution mechanisms in the contract: Parties must anticipate potential issues and include dispute resolution mechanisms in the contract to resolve issues efficiently. In this case, both parties filed lawsuits against each other, resulting in lengthy legal proceedings and costly damages.

2. Consider a computer system called 3P2M in the following figure. The 3P2M system consists of three processors and two shared memories communicating over a shared bus, as shown in the following Figure. The system is operational as long as at least two processors can communicate with at least one of the two memories over the bus.
a) Construct the fault tree model of this system
b) Find all the minimal cut sets
c) Assume all the components fail exponentially with the following failure rates: processors (P1, P2, P3): 0.0001/hour; memories (M1, M2): 0.0001/hour; bus: 0.000001/hour. Find the system reliability at mission time t=100 hours.
1. The probability of the component surviving 200 hours is 0.9608 and still functioning after 400 hours is 0.8862.
2. Assuming all the components fail exponentially, the system's reliability at mission time t = 100 hours is 0.999985.
How to calculate system's reliability?1) To determine the probability that the component survives 200 hours, we need to use the survival function, which is the complement of the cumulative distribution function (CDF).
The CDF gives the probability that the component fails before or at time t, and is given by:
F(t) = 1 - e^(-∫z(u)du), where the integral is taken from 0 to t.
In this case, the failure rate function is z(t) = 2.0 × 10⁻⁶ t/hour for t > 0, so the integral becomes:
∫z(u)du = ∫2.0 × 10⁻⁶ u du = 10⁻⁶ u² + C,
where C is a constant of integration. Evaluating this integral from 0 to 200 hours:
∫0²⁰⁰ z(u)du = 10⁻⁶ (200)² = 0.04
So the CDF at 200 hours is:
F(200) = 1 - e^(-0.04) ≈ 0.0392
Therefore, the probability that the component survives 200 hours is:
P(T > 200) = 1 - F(200) ≈ 0.9608
To determine the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, we need to use the conditional probability formula:
P(T > 400 | T > 200) = P(T > 400 and T > 200) / P(T > 200)
The numerator represents the probability that the component survives beyond 400 hours given that it has already survived 200 hours, while the denominator represents the probability that the component survives beyond 200 hours.
The joint probability of surviving beyond 400 and 200 hours is:
P(T > 400 and T > 200) = P(T > 400)
since if the component survives beyond 400 hours, it necessarily also survives beyond 200 hours.
The probability of surviving beyond 400 hours is:
P(T > 400) = 1 - F(400) = 1 - (1 - e^(-∫z(u)du)) = e^(-∫z(u)du)
Using the same integral as before:
∫0⁴⁰⁰ z(u)du = 10⁻⁶ (400)² = 0.16
So:
P(T > 400) = e^(-0.16) ≈ 0.8521
The probability of surviving beyond 200 hours was found to be approximately 0.9608 in part (1).
Therefore, the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours is:
P(T > 400 | T > 200) = P(T > 400 and T > 200) / P(T > 200)
= P(T > 400) / P(T > 200)
= (e^(-0.16)) / (0.9608)
≈ 0.8862
2) a) Fault tree model of the 3P2M system:
1
/ | \
P1 P2 P3
| | |
1| 1| 1|
| | |
B B B
| | |
1| 1| 1|
| | |
M1 M2 M1
\ / /
\ / /
1 1
where P1, P2, and P3 are the processors, M1 and M2 are the memories, B is the bus, and the numbers above the components represent their probabilities of not failing.
b) Minimal cut sets:
{P1, P2, M1}
{P1, P2, M2}
{P1, P3, M1}
{P1, P3, M2}
{P2, P3, M1}
{P2, P3, M2}
c) To calculate the system reliability, we can use the following formula:
R = e^(-λt)
where R is the system reliability, λ is the failure rate, and t is the mission time.
Using this formula, we can calculate the reliability of each component:
Processor: Rp = e^(-0.0001 × 100) = 0.9048
Memory: Rm = e^(-0.0001 × 100) = 0.9048
Bus: Rb = e^(-0.000001 × 100) = 0.9999
Next, use the minimal cut sets to calculate the system reliability. The minimal cut sets are:
{P1, M1, M2}
{P2, M1, M2}
{P3, M1, M2}
{P1, P2, M1}
{P1, P2, M2}
{P1, P3, M1}
{P1, P3, M2}
{P2, P3, M1}
{P2, P3, M2}
The system reliability can be calculated using the following formula:
Rsys = 1 - Σ(Ri × Π(Rj))
where Ri is the reliability of the i-th minimal cut set, and Π(Rj) is the product of the reliabilities of all components in the j-th minimal cut set.
Using this formula, calculate the system reliability:
Rsys = 1 - [(0.0952 × 0.0952 × 0.0952) + (0.0952 × 0.0952 × 0.0952) + (0.0952 × 0.0952 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952)]
Rsys = 0.999985
Therefore, the system reliability at mission time t=100 hours is approximately 0.999985.

Write a program that computes a patient's bill for a hospital stay. The different components of the program are
• The PatientAccount class will keep track of the patient's charges. It will keep track of the number of days spent in the hospital.
• The surgery method will have the charges for at least five types of surgery. It will update the charges member variable. A data file will contain at least five types of surgery and its cost. Both type and cost will be separated by commas.
• The pharmacy method will have the charges for at least five types of medication. It will update the charges member variable. A data file will contain at least five types of medication and its cost. Both type and cost will be separated by commas
• The dayCharge method will update the days sent member variable.
• The setName method will assign the name of the patient
• Each day in the hospital costs $1,000
The program will have a menu that allows the user to enter type of surgery, enter type of medication, number of days in the hospital and check the patient out of the hospital.
When the patient checks out, the total charges will be displayed.
(LOOK AT PIC BELOW, PYTHON)
here's an example implementation of the program in Python
class PatientAccount:
def __init__(self, name):
self.name = name
self.days_spent = 0
self.charges = 0
def surgery(self, surgery_type, cost):
self.charges += cost
print(f"{surgery_type} surgery added to charges.")
def pharmacy(self, medication_type, cost):

cost = float(input("Enter cost: "))
patient.surgery(surgery_type, cost)
elif choice == "2":
medication_type = input("Enter type of medication: ")
cost = float(input("Enter cost: "))
patient.pharmacy(medication_type, cost)
elif choice == "3":

patient.setName(name)
elif choice == "5":
total_charges = patient.getTotalCharges()
break
else:
print("Invalid choice. Try again.")
print("Thank you for using the hospital bill program.")
Explanation:
This program defines a PatientAccount class that keeps track of the patient's name, days spent in the hospital, and charges. It also includes methods to add surgery and medication charges, add day charges, and set the patient name. The getTotalCharges method calculates the total charges based on the number of days spent in the hospital and the accumulated charges.
The program uses a while loop to display a menu of options and accept user input. The user can add surgery or medication charges, add a day charge, set the patient name, or check out and calculate the total charges. The loop continues until the user chooses to check out.

Write a class named Car that has the following member variables:
• Year. An int that holds the car's model year.
• Make. A string object that holds the make if the car.
• Speed. An int that holds the car's current speed
In addition, the class should have the following member functions program that implements class structure.
• Constructor. The constructor should accept the car's vear and make arguments and assign these values to the object's year and make member variables. The constructor should initialize the speed member variable to 0.
• Accessors. Appropriate accessor methods should be created to allow values to be retrieved from the object's year, make, and speed member variables
• accelerate. The accelerate method should add 5 to the speed member variable each time it is called.
• brake. The brake method should subtract from the speed member variable each time it is called.
Write a program that will create the Car object. It will ask the users for the number of times the car will accelerate and brake.
(LOOK AT PIC BELOW, PYTHON))
An example implementation of the Car class in Python is given as follows:
class Car:
def __init__(self, year, make):
self.year = year
self.make = make
self.speed = 0
def get_year(self):
return self.year
def get_make(self):
return self.make

self.speed += 5
def brake(self):
self.speed -= 5
if self.speed < 0:
self.speed = 0
car = Car(2022, "Tesla")
accelerate_times = int(input("How many times do you want to accelerate? "))
brake_times = int(input("How many times do you want to brake? "))

car.accelerate()
print("Accelerating... Speed is now", car.get_speed())
for i in range(brake_times):
car.brake()
print("Braking... Speed is now", car.get_speed())
What is the explanation for the above response?This program creates a Car object with the year 2022 and make "Tesla", and then prompts the user for the number of times to accelerate and brake. It uses a for loop to call the accelerate and brake methods on the Car object the specified number of times, and prints the updated speed after each call.
The prompt requires creating a Car class with member variables year (int), make (string), and speed (int), as well as appropriate member functions, including constructor, accessors, accelerate (adds 5 to speed), and brake (subtracts from speed). The program should allow user input for how many times the car should accelerate and brake.
