Question 1

What is the difference between while and do while loop?

Answer 1

While loop is an entry controlled loop ie it checks the condition before executing the loop and if the conditionimplies T loop is executed else it is terminated whereas, do while loop is an exit controlled loop. In do while loop, the loop body is executed and then the condition is checked. In do while loop, loop is executed atleast once and loop terminates after the condition is F.
