Bulls and Cows Classic

The program generates a 4-digit secret number. All digits are different. Try to guess generated number. Play by entering your guess using digits pad and clicking ENTER button to check your entry. Once you guess the number, you win the game.

A bull (B) is a digit which is in the number and in the correct position.
A cow (C) is a digit which is in the number but in the wrong position.

Example: secret number is 8207

1st guess: 1234 (1B)
The bull is 2 - digit is in the number and in the correct position

2nd guess: 1705 (1B 1C)
The bull is 0 - digit is in the number and in the correct position
The cow is 7 - digit is in the number and but in the wrong position

3rd guess: 8207 (4B)
All digits are bulls because they are all in the number and in the correct positions
