Difference between while and do-while
The while statement verifies the condition before entering into the loop to see whether the next loop iteration should occur or not. The do-while statement executes the first iteration without checking the condition, it verifies the condition after finishing each iteration. The do-while statement will always execute the body of a loop at least once.
