This is an old computer game from the $70\text{'}$s$.$I believe the board game Master Mind was inspired by this game.$$ It is guessing game where you are trying to guess a secret $4$ digit "code".$$After the user enters a $4$ digit guess, the program should reply with how many digits are the correct number and in the correct order, these are called Bulls and signified with a B$.$ If a digit guess is correct, but in the wrong order $($location$)$ then it$,$ this is called a Cow, and signified with a C$.$

It is claimed that you should be able to solve it in $7$ games.....see if you can.

For turn$-$in run the program and play until you have won.$$ Then copy your output, and place it below your program as a comment.$$ Your program output could look like this for a secret code of $5268$:
