Explanation:
- Both types of loops repeat a block of statements until some condition becomes false.
- The main difference is that in a while loop, the test-condition is tested at the beginning of the loop, and in a do-while loop, the test-condition is tested at the end of the loop.
- It is possible that the body of a while loop might not be executed at all.
- However, The body of a do-while loop is executed at least once since the test-condition for ending the loop is not tested until the body of the loop as been executed.
- While loop is an entry-controlled loop.
- The do-while loop is an exit-controlled loop.
