Counter-controlled loop type
Counter-controlled loop type

Loop control variable tested
Loop control variable tested
The loop condition is checked before each execution of the loop body.

Study Notes
Loop Types and Concepts
- A counter-controlled loop iterates a specific number of times, using a counter variable that keeps track of the number of iterations.
- A pre-test loop, such as a
whileloop, checks the loop control variable before executing the loop body, ensuring the condition is met before any code within the loop runs. - An indefinite loop is user-controlled, allowing for an unknown number of iterations where the user determines when to stop the loop.
- A loop structure facilitates the repeated execution of a block of statements, allowing for efficient coding and reducing redundancy.
- An iteration refers to a single execution of the loop body, allowing the loop to perform its designated operations.
