Master Mind (Cows & Bulls)

[todor81]

Hi, there
can anybody tell me a strategy to write a C program, that plays Master mind (Cows & Bulls):
- the computer must guess the player's number in 7 suggestions.
- meanwile the computer plays "unhonest" game - it doesn't have a number and succesfully answers the user's suggestions so it doesn't lie.

10x a lot.

can you give me a little more detail on the game. Like what kind of answers the computer answers? and the number range you can pick. Nail the code

The numbers are with four digits and no digits can be repeated.
1234 - yes
1165 - no
The user selects a number (e.g. 7642) and the PC must guess it in 7 moves.
PC says 1234 - there is 1 cow and 0 bulls, because 2 is in the number, but not in the right place.
PC says 7624 - there are 2 bulls (7 and 6, because they are in the right position) and 2 cows (2 and 4).
At last 7642 - 4 bulls and the game's finished.
