Count-controlled iteration - GCSE Computer Science Definition

Count-controlled iteration is a programming concept where a loop repeats a set number of times, as specified by a count variable. In GCSE Computer Science, this is commonly implemented using a "for" loop, which executes a block of code a predetermined number of times. The loop typically involves initialising a counter, running the loop's instructions while a condition based on the counter is true, and updating the counter with each iteration. This approach is useful when the number of repetitions is known in advance, such as iterating over elements in an array or performing a task a specific number of times. By mastering count-controlled iteration, students can efficiently automate repetitive tasks in their programs.
