What term in modular design is also referred to as looping?

In modular design, the term that is often associated with looping is iteration. Iteration refers to the process of repeating a set of instructions or a block of code until a certain condition is met. This concept is critical in programming and system design because it allows for efficient performance of repetitive tasks without the need to write the same code multiple times.

For example, when you need to process a list of items or repeat an action until a specific result is achieved, you would implement iteration techniques, such as loops (for, while, etc.), to carry out these tasks concisely.

Though recursion may seem similar, as it involves a function calling itself, it is a different concept. Recursion typically breaks a problem into smaller sub-problems, rather than straightforwardly repeating a sequence of instructions. Sequence refers to the order of execution of statements in a program but does not imply repetition. A function is a reusable block of code that performs a specific task when called, but it doesn't inherently involve repetition unless combined with looping constructs. Thus, iteration is the correct term related to looping in modular design.
