C++ doWhile Loop Control Structure

In this Tutorial we will understand and learn the working of dowhile Loop statements in C++ programming language.

Loops are used in programming to repeat a specific block until some end condition is met.

A do while loop is similar to a while loop, except that a do while loop is guaranteed to execute at least one time. This is because unlike for and while loops, a do while loop checks its condition at the bottom of the loop structure. This is the only difference between a do while loop and other loops.

Working of Do While Loop
  • The codes inside the body of loop is executed at least once for the first time.
  • Then, the test condition is checked.
  • If the test condition is true, the body of loop is executed. This process continues until the test expression becomes false.
  • When the test condition is false, do…while loop is terminated.
