Write a Console Java program that asks the user to enter one sentence on the keyboard. Output on the console:
1) The number of words in the sentence
2) A count of each alphabet in the sentence in alphabetical order (ignore zero counts, ignore Upper/Lowercase difference. That is, count 'A' and 'a' as the same) . Assume that the user will enter a sentence with alphabets. No need to validate user entry. Example: Sentence: This is a great Fall Semester Number of words: 6 a-3, e-4. f-1, g-1, h-1, i-2, l-2, m-1, r-2 , s-4, t-3
Answers
Answer:
Here is the JAVA program:
import java.util.Scanner; //to accept input from user
public class Main{ //class name
public static void main(String[] args){ //start of main function
String sentence; //to store the input sentence
int i, length; //declare variables
int count[] = new int[256]; //creates a counter array
Scanner input = new Scanner(System.in); //creates Scanner class object to accept input from user
System.out.println("Enter a sentence: "); //prompts user to enter a sentence
sentence = input.nextLine(); //scans and reads the entire sentence string from user
String[] words = sentence.split("\\s+"); //splits the sentence into an array with separator as one or more white spaces and stores this array in words
System.out.println("Number of words: " + words.length); //display the number of words in sentence by using length which returns the length of the words array
sentence = sentence.toLowerCase(); // converts the sentence into lower case to ignore case sensitivity
sentence = sentence.replaceAll("\\s+",""); //removes the empty spaces from sentence
length = sentence.length(); //stores the length of the sentence string into length variable
for (i = 0; i < length; i++) { //iterates through the length of the sentence
count[(int) sentence.charAt(i)]++; } //counts occurrence of each alphabet in the sentence and stores it in count array
for (i = 0; i < 256; i++) { displays occurrence of alphabet in sentence
if (count[i] != 0) { //if count array is not empty
System.out.println((char) i + "-" + count[i]); }}}}
//prints each alphabet and its count
Explanation:
The program prompts the user to enter a sentence. Suppose the user enters "We won" so
sentence = "We won"
Now this sentence splits into an array with white space as separator and stored in words array. So words array has two words of sentence now i.e. "We" and "won"
Next words.length is used to return the length of words array. So length of words array is 2 hence
number of words = 2
Next the sentence is converted to lower case and spaces are removes so sentence becomes:
wewon
sentence.length() returns the length of sentence which is 5.
Next the for loop is used. At each iteration of this loop occurrence each character of sentence is added to the count[] array. charAt() is used to return a character at each index position of string. So the frequency of every character is counted and stored in count array.
Next is a for loop that is used to display each alphabet in the sentence along with its frequency in alphabetic order.
Hence the entire program gives the output:
Number of words: 2 e-1 n-1 o-1 w-2
The screenshot of the output of example given in the question is attached.

P5.30 Having a secure password is a very important practice, when much of our information is stored online. Write a program that validates a new password, following these rules: •The password must be at least 8 characters long. •The password must have at least one uppercase and one lowercase letter. •The password must have at least one digit. Write a program that asks for a password, then asks again to confirm it. If the passwords don’t match or the rules are not fulfilled, prompt again. Your program should include a function that checks whether a password is valid.
Answers
Answer:
def check_password(password):
is_short = False
has_uppercase = False
has_lowercase = False
has_digit = False
if len(password) < 8:
is_short = True
for p in password:
if p.isupper():
has_uppercase = True
if p.islower():
has_lowercase = True
if p.isdigit():
has_digit = True
if is_short == False and has_uppercase and has_uppercase and has_digit:
return True
else:
return False
while True:
password = input("Enter your password: ")
password2 = input("Enter your password again: ")
if password == password2 and check_password(password):
break
Explanation:
Create a function named check_password that takes one parameter, password
Inside the function:
Initialize the is_short, has_uppercase, has_lowercase, and has_digit as False. These variables will be used to check each situation
Check the length of the password using len() method. If it is smaller than 8, set is_short as True
Create a for loop that iterates through password. Check each character. If a character is uppercase, set the has_uppercase as True (use isupper() function). If a character is lowercase, set the has_lowercase as True (use islower() function). If a character is a digit, set the has_digit as True (use isdigit() function).
When the loop is done, check the value of is_short, has_uppercase, has_lowercase, and has_digit. If is_short is False and other values are True, return True. Otherwise, return False
Create an indefinite while loop, that asks the user to enter password twice. Check the entered passwords. If they are equal and the check_password function returns True, stop the loop. This implies that both passwords are same and password is valid.

caption label
Explanation:
A user is asked to type a caption for a photo in a web form's text field. If the caption didn't end with a punctuation mark (. ! ?), a period should automatically be added. A common error is to end with a comma, which should be replaced by a period. Another common error is to end with two periods, which should be changed to one period (however, ending with three periods (or more) indicates elipses so should be kept as is). The corrected caption is output. If the input is "I like pie", the output is "I like pie." If the input is "I like pie!", the output remains "I like pie!" If the input is "Coming soon…", the output remains "Coming soon…"
Answers
Answer:
Here is the c++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects cin cout
int main() { //start of main function
string caption; //stores the caption
int last_index; //stores the index position of the last character of caption
char last_character; //stores the last character of the caption
cout<<"Please type a caption: "; //prompts user to enter a caption
getline(cin, caption); //reads the complete line of caption from user
last_index = caption.size() - 1; //sets the last_index to the last character of caption
last_character = caption.at(last_index); //sets the last_character to the last character positioned by last_index
if ((last_character == '!') || (last_character == '?')) {} /* checks if the last character of the caption is either ! or ? and if this statement evaluate to true then this does not require any action */
else if (last_character == ',') { //checks if the last character of the caption is a comma
caption.at(last_index) = '.'; } //if the else if condition is true then replace that comma with a period .
else if (last_character != '.') { //checks if the caption does not end with ! ? , .
caption.push_back('.');} //append period to the caption . if above if else condition is true
else if ((last_index > 0) && (last_character == '.') && (caption.at(last_index - 1) == '.')) { //checks if the caption has two periods .
if ((last_index > 1) && (caption.at(last_index - 2) == '.')) {} //checks if the caption has three periods and does nothing if this is true
else { //if caption has two periods
caption.pop_back();}} //removes one period if caption has two periods .
cout << caption << endl;} //displays the caption
Explanation:
I will explain the above program with an example
Lets say user input the caption: I like pie
So
caption = " I like pie"
The first if condition if ((last_character == '!') || (last_character == '?')) evaluate to false because the last character of the caption is not an exclamation mark of a question mark. So the program moves to the next else if statement:
else if (last_character == ',') This statement is also false because the last character of the caption is not a comma. So the program moves to the next else if part.
else if (last_character != '.')
Now this statement evaluate to true because the last character of the caption is not a period . sign. So this part is executed. It has a statement:
caption.push_back('.');
Now this statement uses push_back() method which adds new character i.e. period '.' at the end of the caption string, increasing its length by one.
So the output of the program is:
I like pie.
If the caption = " I like pie!" then this if ((last_character == '!') || (last_character == '?')) condition executes and since it does nothing {} so the caption remains as it is and the output is:
I like pie!
If the caption = "Coming soon…" then this else if ((last_index > 0) && (last_character == '.') && (caption.at(last_index - 1) == '.')) condition executes which checks if the caption has two period. When this condition evaluates to true then the statement inside this else if condition executes which is: if ((last_index > 1) && (caption.at(last_index - 2) == '.')) and this checks if the caption has three periods. Yes the caption has three periods so it does nothing and the caption remains as it is and the output is:
Coming soon…
However if the caption is Coming soon.. with two periods then the else part inside else if ((last_index > 0) && (last_character == '.') && (caption.at(last_index - 1) == '.')) condition executes which is: caption.pop_back(); and this removes one period from the caption and the output is:
Coming soon.

Why is it important for element IDs to have meaningful names?
Answers
Answer:
Explanation:
In programming, it is very important that element ID's have meaningful names because it allows anyone reading the code to be able to easily identify what that element is and where it is most likely to be found in the code. This also applies to variables in every programming language. The clearer and more unique the name is the easier it becomes to know what that variable or element ID is representing which ultimately makes reading and debugging the code that much easier. This means that the entire process becomes more efficient as well.
It is vital for element IDs to have meaningful names due to the fact that it allows easy identification of the codes.
Element IDs refer to the id property of the interface of the element. It should be noted that the id property is unique in a document.
Element IDs should have meaningful names due to the fact that it allows east identification of the codes. This makes it easy for the person reading the code to identify them easily. The uniqueness of an element ID is vital to know what it represents.

This assignment involves writing a Python program to compute the average quiz grade for a group of five students. Your program should include a list of five names. Using a for loop, it should successively prompt the user for the quiz grade for each of the five students. Each prompt should include the name of the student whose quiz grade is to be input. It should compute and display the average of those five grades and the highest grade. You should decide on the names of the five students. Your program should include the pseudocode used for your design in the comments.

Answer:
Here is the Python program along with the comments of program design
#this program is designed to compute the average quiz grades for a group of five students
students = ["Alex", "John", "David", "Joseph", "Mathew"] #create a list of 5 students
grades = [] # create an empty list to store the grades in
for student in students: #loop through the students list
grade = input("Enter the quiz grade for "+student+": ") #prompt the user for the quiz grade of each student
#store the input grades of each student to grade
grades.append(int(grade)) # convert the grade to an integer number and append it to the list
print("Grades are:", grades) #display the grades of five students
average = sum(grades) / len(grades) #compute the average of five grades
print("The average of grades is:", average) #display the average of five grades
highest = max(grades) #compute the highest grade
print("The highest grade is:", highest) #print highest grade
Explanation:
The program first creates a list of 5 students who are:
Alex
John
David
Joseph
Mathew
It stores these into a list named students.
Next the program creates another list named grades to store the grades of each of the above students.
Next the program prompts the user for the quiz grade for each of the five students and accepts input grades using input() method. The statement contains student variable so each prompt includes the name of the student whose quiz grade is to be input. Each of the grades are stored in grade variable.
Next the append() method is used to add each of the input grades stored in grade to the list grades. The int() method is used to first convert these grades into integer.
Next print() method is used to display the list grades on output screen which contains grades of 5 students.
Next the average is computed by taking the sum of all input grades and dividing the sum by the total number of grades. The sum() method is used to compute the sum and len() method is used to return the number of grades i.e. 5. The result is stored in average. Then the print() method is used to display the resultant value of average.
At last the highest of the grades is computed by using max() method which returns the maximum value from the grades list and print() method is used to display the highest value.

Consider the GBN protocol with a sender window size of 4 and a sequence number range of 1,024. Suppose that at time t, the next in-order packet that the receiver is expecting has a sequence number of k. Assume that the medium does not reorder messages. Answer the following questions: What are the possible sets of sequence numbers inside the sender’s window at time t? Justify your answer. What are all possible values of the ACK field in all possible messages currently propagating back to the sender at time t? Justify your answer.
Answers
Answer:
Follows are the solution to this question:
Explanation:
In point a:
N = Size of window = 4
Sequence Number Set = 1,024
Case No. 1:
Presume the receiver is k, and all k-1 packets were known. A window for the sender would be within the range of [k, k+N-1] Numbers in order
Case No. 2:
If the sender's window occurs within the set of sequence numbers [k-N, k-1]. The sender's window would be in the context of the sequence numbers [k-N, k-1]. Consequently, its potential sets of sequence numbers within the transmitter window are in the range [k-N: k] at time t.
In point b:
In the area for an acknowledgment (ACK) would be [k-N, k-1], in which the sender sent less ACK to all k-N packets than the n-N-1 ACK. Therefore, in all communications, both possible values of the ACK field currently vary between k-N-1 and k-1.
