Task: Write a C program to play Mastermind against a human codebreaker. Mastermind is a simple two-player code-breaking board game. In the game, one player is the codemaker and the other is the codebreaker. The codemaker secretly selects a code consisting of an ordered sequence of four colors (c1, c2, c3, ca), each chosen from a set of six possible colors, with repetitions allowed. The codebreaker then tries to guess the code by repeatedly proposing a sequence of colors (g, g2, g3, ga). After each guess, the codemaker tells the codebreaker two numbers (b, w): the number of correct colors in the correct positions (b) and the number of colors that are part of the code but not in the correct positions (w) For example, consider the six colors: Blue, Green, Orange, Purple, Red, and Yellow. If the code is (B, G, 0, 0) and the codebreaker's guess is (O, G, P, 0), then the codemaker's response would be (2, 1), since the codebreaker has guessed the G and the second O correctly and in the correct positions, while having guessed the first O correctly but in the wrong position The codebreaker continues guessing until either the codebreaker guesses the code correctly or until twelve incorrect guesses are made Additio nal Specifications: The code to be guessed should be given as a command-line argument Use standard input and standard output only The input/output must exactly match the samples given, character for character Deliverables: A file named mastermind.c containing the ANSI C source code. The submission will not receive a grade if the file mastermind.c produces compilation warnings or errors. So, before submitting your solution, make sure it compiles cleanly using the gcc compiler as follows: $. gcc -ansi -Wall -Wextra -Werror mastermind . c Input/Output Sample 1 $ ./a.out PORG Available Colors: (B)lue (G) reen (0)range (P)urple (R)ed (Y)ellow No. guesses left: 12 Enter your guess: BB00 Feedback: 0, 1 No. guesses left: 11 Enter your guess: BBGG Feedback: 1, No. guesses left: 10 Enter your guess: OPPG Feedback: 1, 2 No. guesses left: 9 Enter your guess: OPYG Feedback: 1, 2 No. guesses left: 8 Enter your guess: PORG Feedback: 4, 0 YOU WIN!
