In programming, what control structure repeatedly executes a block of instructions while a specified condition remains true (for example, a while, for, or do-while statement)?
Sequence
Recursion
Loop
Iteration
A loop is a control structure that enables a program to execute a block of code multiple times as long as a given Boolean condition evaluates to true. Each pass through the loop body is called an iteration, but the term iteration can also refer broadly to the overall process of repeated execution. Recursion, by contrast, involves a function calling itself, and sequence simply describes statements running once in order, without repetition.
