Which term best matches 'Part of a program that repeats itself, to prevent the need for the same piece of code to be typed out multiple times'?

Which term best matches 'Part of a program that repeats itself, to prevent the need for the same piece of code to be typed out multiple times'?

• A. Function
• B. Expression
• C. Input
• D. Loop

Answer: (D)

Repetition of a block of code is handled by a loop. A loop runs its body multiple times, so you don’t have to copy-paste the same instructions over and over. It keeps programs shorter and easier to change because you can control how many times the block runs or keep running until a condition changes. You’ll see common forms like for loops, while loops, and do-while loops. If you think about organizing code into reusable pieces, a function can be called multiple times, but it doesn’t by itself make code repeat automatically—the loop is what causes actual repetition. An expression computes a value, and input brings data into the program, neither of which implies repeating a block of code. So the term that fits best is loop.
