Explain do-while statement with syntax and example

C's do-while statement has the form:

  do
                                statement;
                                while (expression);
For example:
  int x=3;
                main()
                                { do {
                                               printf("x=%d$\setminus$n",x-);
                                               }
                                while (x>0);
                                }

..outputs:-
  x=3

                x=2

                x=1

NOTE: The postfix x- operator which uses the current value of x while printing and then decrements x.
