What are the main difference between for loop,while loop and do while loop?

Answer 1

The difference is between them is the use when we know the number of times that will be the work to be done we better use the FOR loop, in case we don't know the number of times we use the While loop or the do while loop, and in case our work need to execute at least one time we should work with do while loop

Answer 2

there is no difference between this three loops. the output of all of this is same only the way of working and the structure is different.
mostly the for loop is used.
