The do while loop

The “do while loop” is almost the same as the while loop.

The “do while loop” has the following form:

{ do something;} while (expression) ;

Do something first and then test if we have to continue.

The result is that the loop always runs once. (Because the expression test comes afterward).

example:

        int main()

        {
               int counter, howmuch;

               scanf("%d", &howmuch);

               counter = 0;

do

                       counter++;

                       printf("%d\n", counter);

               while ( counter < howmuch);

               return 0;

Note: There is a semi-colon behind the while line.
