A "while loop" is a fundamental control flow structure in programming that repeatedly executes a block of code as long as a specified condition remains true. This type of loop is particularly useful when the number of iterations is unknown or depends on a dynamic condition.
While loops are versatile and allow for dynamic iteration, but it's essential to ensure that the condition eventually becomes false to prevent an infinite loop. Careful consideration of the loop's control flow and exit conditions is crucial to avoid unintended behavior.
