Condition-controlled iteration - GCSE Computer Science Definition

Condition-controlled iteration is a programming concept where a set of instructions is repeatedly executed as long as a specified condition remains true. This is commonly implemented using loops, such as "while" loops, in various programming languages. For students studying GCSE Computer Science, it's important to understand that the loop will continue to cycle through its block of code until the condition it is based on evaluates to false. This type of iteration is particularly useful when you do not know beforehand how many times the loop will need to run, as the repetition depends on the dynamic evaluation of the condition rather than a fixed number of iterations.
