C++ do-while Loop: Purpose Explained

The purpose of the do-while statement in C++ is to execute a block of code, check if the condition is true after executing the block, and continue executing the block until the condition is false. Unlike the while statement, the do-while statement will execute the block at least once before determining whether to continue based on the condition. This feature makes the do-while statement suitable for situations where it is necessary to execute the block once before deciding whether to execute it again.
