A do while loop is very much the same as while loops with the exception that a do while loop evaluates its expression after the body. This means that a do while loop will always execute at least once before checking the loop condition

int x= 10000000;// Ten million
do{
   x++;
}while(x < 10);
// x now = 10000001 

The code will execute the contents of the do block (x++), once, before the while condition is tested even though the condition evaluates to false.

Let's look at one more type of loop before we get back to the game.
