A while loop executes a block of code as long as the condition is true; it does not run if the initial condition is false. This control structure is crucial for repetitive tasks in programming but must have a proper exit condition to prevent infinite loops.
The correct definition of a while loop is: A) While loop executes while the condition is true.
A while loop continually executes a block of code as long as the given condition remains true. Once the condition evaluates to false, the loop stops executing.
A while loop is a fundamental control structure in programming that allows for repeating a set of instructions under a certain condition. The key aspect of a while loop is that it checks the condition before executing the block of code, meaning that if the initial condition is false, the code inside the loop will not execute even once. This is in contrast to a do-while loop, which guarantees at least one execution of the block because it checks the condition after the code has been executed. While loops are used to perform repetitive tasks in code, but they must be written with care to ensure that they have an exit condition, otherwise, they can lead to an infinite loop scenario.
Understanding the behavior of while loops is critical for implementing control flow effectively in programming. The given definition A is the only correct choice that accurately represents the functionality of a traditional while loop.
