Difference between “while” loop and “do while” loop

Question

What is the difference between while loop and do while loop. I used to think both are completely same.Then I came across following piece of code:

do {
                


        

Answer 1

While:

1. entry control loop

2. condition is checked before loop execution

3. never execute loop if condition is false

4. there is no semicolon at the end of while statement

Do-while:

1. exit control loop

2. condition is checked at the end of loop

3. executes false condition at least once since condition is checked later

4. there is semicolon at the end of while statement.
