Send characters from a string in reverse order to output window

#include <cstdlib>

    /*The for statement has three arguments in order to accomplish this task
    1] int i = choose.length()-1 gets the length of the string and subtracts
       the null character so you dont get a blank space in the return
       try it both ways to see what i mean
    2] i greater than zero to terminate loop is self explanatory.
    3] i-- counts backwards to give the desired affect.

            you can use them as such, so i is now the length of your string and
