Which type of control construct allows a block of code to repeat until a certain condition is fulfilled?

The control construct that allows a block of code to repeat until a certain condition is fulfilled is known as a conditional loop. This type of loop continuously executes the code within its block as long as a specific condition remains true. When the condition becomes false, the loop stops executing. This feature is particularly useful for scenarios where the number of iterations is not predetermined and depends on dynamic conditions, such as user input or state changes in a program.

In programming, conditional loops can take forms such as "while" loops or "repeat-until" loops, which directly embody this idea of repeating based on a specified condition. This makes them distinct from other constructs that either execute a set number of times or utilize function calls to achieve repetition.
