👉 A "while loop" is a control structure in programming used to execute a block of code repeatedly while a specified condition remains true. Unlike a traditional for loop, which iterates over a fixed range or until a specific event occurs, a while loop continues to run as long as the condition specified at the start of the loop evaluates to true. This makes it particularly useful for situations where the number of iterations is unknown or dependent on a dynamic condition, such as reading input until a specific value is entered. The loop updates the condition within its body until it becomes false, at which point the loop terminates and execution moves to the next line of code after the loop.
