Do While Loop Program in C++

This C++ program demonstrates the use of do-while loop. The do-while loop works the same way as a while or for loop with a difference that the condition for execution of the next iteration is checked after the execution of statements inside the block.

Here is the source code of the C++ program demonstrates the use of do-while loop. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.
