Which coding structure is executed multiple times until a condition is no longer true?

The coding structure that is executed multiple times until a condition is no longer true is the WHILE loop. A WHILE loop repeatedly executes a block of code as long as a specified condition remains true. This is particularly useful for situations where the number of iterations is not predetermined and depends on dynamic conditions that may change during program execution.

For example, a WHILE loop can be used in scenarios like counting until a certain limit is reached, processing items in a list until none remain, or continuously prompting a user for input until they provide a valid response. The process stops only when the condition evaluates to false, making it a flexible tool for creating repetitive tasks based on ongoing conditions.

In contrast, an IF statement evaluates a condition only once and executes code depending on whether the condition is true or false, while a FOR loop is typically used when the number of iterations is known beforehand. A SELECT statement is used for branching logic based on multiple conditions but does not involve repetition of code. Thus, the WHILE loop stands out as the correct choice for executing code repeatedly based on a condition.
