do                       do-while Statement
 
 do
     statement
 while (expression);
 
    The do-while statement executes the statements in the body, and then
    evaluates the looping criteria at the end of the loop.  If the
    expression is true, the loop is re-entered and the body is executed
    again. When the expression tests false control is passed to the next
    statement following the loop.
 
      Notes:    With the do-while construct, the statements in the body
                are always executed at least once.  That's because the
                condition is tested at the end of the loop, rather than
                at the beginning--as in the `for' and `while' statements.
 
                You can terminate a do statement prematurely by using a
                continue or break statement.
 
  -------------------------------- Example ---------------------------------
 
           do {              /* Use braces for multiple statements */
               process();
               i++;
           } while (i < 20);
