You are writing an algorithm and want to tell the computer what to do if the
user does not perform an action. Which type of statement should you include
in your algorithm?
A. Return
B. When-if
C. If-else
D. And-or
Answer:
you are writing an algorithm and went to tell computer what to do If the return
The type of statement, i.e., if-else should be include in your algorithm. The correct option is C.
What is if-else statement?An "if-else" statement is a conditional statement that determines whether a particular condition is true or false and then executes different code based on the outcome of that evaluation.
An "if-else" statement could be used in the context of a user action to check whether the user has performed a specific action and then execute different code depending on whether the user has performed that action or not.
To exit a function and return a value to the calling code, use a "return" statement. A "when-if" statement and a "and-or" statement are not standard programming constructs and are rarely used in code.
Thus, the correct option is C.

Which term best describes the set that makes up an algorithm?
A. Steps
B. Documents
C. Statements
D. Patterns
Answer:
A
Explanation:
An algorithm is a series of steps to get to a final result.
The term that best describes the set that makes up an algorithm is steps. The correct option is A.
What is algorithm?An algorithm is a set of step-by-step instructions that are followed in order to complete a specific task or solve a particular problem.
Each step in the algorithm is typically a distinct command or operation designed to accomplish a specific goal or modify a specific aspect of the data being processed.
Documents, statements, and patterns are not the best terms to describe the collection of elements that comprise an algorithm.
While an algorithm can be documented or described in written or visual form, the term "documents" does not adequately describe the nature of the instructions themselves.
Similarly, while an algorithm may be made up of individual commands or operations, the term "statements" does not convey the concept of a step-by-step process.
Finally, while an algorithm may contain repeating patterns or structures, the term "patterns" does not imply a linear sequence of steps that must be performed in a specific order.
Thus, the correct option is A.
