Description

SPECIFICATIONS

Write a program called mastermind; it will be an implementation of the famous game.

NAME

my_mastermind

SYNOPSIS

my_mastermind [-ct]

DESCRIPTION

Mastermind is a game composed of 9 pieces of different colors. A secret code is then composed of 4 distinct pieces.

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 butthat is not in a good position.

You must read the player's input from the standard input.

Your program will also receive the following parameters: -c [CODE]: specifies the secret code. If no code is specified, a random code will be generated. -t [ATTEMPTS]: specifies the number of attempts; by default, the playerhas 10 attempts.

Example 00

PROMPT>./my_mastermind -c "0123"
Will you find the secret code?
Please enter a valid guess

Round 0
>1456
Well placed pieces: 0
Misplaced pieces: 1

Round 1

Wrong input!
>4132
Well placed pieces: 1
Misplaced pieces: 2

Round 2

Congratz! You did it!

Technical information

  1. you must create a Makefile, and the ouput is the command itself It will contain rule all/clean/fclean (re => fclean + all)

  2. You can use:

  • printf(3)
  • write(2)
  • read(2)
  • rand() (/ srand())
  • time()
  • atoi()
  • strcmp()
  1. You can NOT use:
  • Any functions/syscalls which does not appear in the previous list
  • Yes, it includes exit

  1. Consider writing a README.md to describe your project and how it works.

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

  3. read() is a syscall difficult to apprehend, you will have time to deal more with it in a later project. In this project, you should read 1 character by 1 (use read(0, &c, 1)) and add them one by one to a buffer until you encounter a newline.

Example:

[/tmp/]bash
bash-3.2$ exit
[/tmp/]

In this example, bash exited successfully and also printed "exit".

Output formats

  1. When your program starts, you must display:
Will you find the secret code?
Please enter a valid guess
  1. When the user wins, you must display:
Congratz! You did it!
  1. When the user enters an invalid code, you must respect the following format:
Well placed pieces: X
Misplaced pieces: Y

X and Y are two digits with the correct values.

Requirements

  • Your code must be compiled with the flags -Wall -Wextra -Werror.
  • Multiline macros are forbidden
  • You should have multiple file .c but it's forbidden to include them (#include another_file.c) use your Makefile to compile them together.
  • Macros with logic (while/if/variables/...) are forbidden

Advanced Testing

Gandalf tests using a synthax similar to this one:

echo "1234
2345
3456" | ./my_mastermind -c 3456

It will hightlight that you are not using read() well.

Hint(s)

  • man 2 read
  • man rand

Makefile, case sensitivity is important.
