Question

Which of the following is used to control the flow of a program?

Answers

Variable
Function
correct

Loop
Array

Explanation

Correct Answer: C) Loop

A loop is used to control the flow of a program by repeatedly executing a block of code as long as a specified condition is true. It allows programs to perform repetitive tasks without writing the same code multiple times.

Common types of loops include for, while, and do-while loops. Loops are crucial for controlling program execution based on conditions and iterating through data structures like arrays or lists.

Why the Other Choices are Incorrect:

A) Variable – A variable is used to store data in a program, such as numbers or text, but it does not control the program's flow. It simply holds values that can be manipulated or referenced during execution.
B) Function – A function organizes code into reusable blocks but doesn’t inherently control the flow. While calling a function executes code, the function itself doesn’t determine iteration or decision-making unless combined with control structures.
D) Array – An array is a data structure that holds multiple values. It’s used for data storage and access, not for directing how or when code runs. Loops often iterate over arrays, but arrays don’t control flow themselves.
