Creating a mastermind game

[dailysflash]

I have an assignment to create a mastermind game where the player has 10 attempts to find the secret code. After each input, the game indicates to the player the number of well placed pieces and the number of misplaced pieces.
Pieces will be '0' '1' '2' '3' '4' '5' '6' '7' '8'.
If the player finds the code, he wins, and the game stops. A misplaced piece is a piece that is present in the secret code but that is not in a good position.

You must read the player's input from the standard input.
You can use:

• printf(3)
• write(2)
• read(2)
• rand() (/ srand())
• time()
• atoi()

You can NOT use:

• Any functions/syscalls which does not appear in the previous list
• Yes, it includes exit

Your mastermind needs to handle the sequence Ctrl + d. It's End Of File. It's consider as a normal execution.

and here is my code

Copied my my IDE.
