number guesser program in c.

    Guess a number  sequence using the limit  (1,6) ,the program will guess the number within  8 steps
you must provide(input)  1. how many terms are in the exact position (first input)
                                         2.how many terms are misplaced (second input)

 try example 1443(i am guessing this..)
guesser output     chooser output
1111                      1   0
2221                      0    1
3313                      1    1
4143                       2    2
1443                       4     0
