    the difference is like this....

    Code:
    while {argument}
        {statement}
    the statements will only be performed if the argument is true, then will continue to loop until false


    Code:
    do
        {statement}
    while {argument}
    the statements will be performed at least once, before the argument is tested. Then if the argument is true it will continue to loop until false.

    I hope this helps

    ...and what rwmarsh said minus the syntax errors:

    Code:
    while (conditional){ 
    }
    
    do {
    } while(conditional);
    His explaination was correct, though.
