Question

Develop a game (i.e., a simple, and text-based version of the Mastermind game) using programming language C. In this last assignment, we are going to create some custom fucntions inside the completeprogram of the Mastermind game. Also those of you who did not receive complete mark from the previous assignment because of any types of errors, have the opportunity to revise and fix your code. If you haven't used arrays to store the hidden code and the player's gusses in your code for assignment 2, you should modify your code and use arrays for this purpose in this assignment as well. In this assignment, you are given the prototype of some custom functions, below. You should implement those functions based on the comments provided for each function. Then, use those functions inside your existing program of the game. The second modification you should do in this assignment is that the player can change the number of hidden digits that they should guess inside the game, and the number of guessing opportunties. In the current version, the number of digits is four, which means your program generates four unique random digits and the player should guess it in maximum ten guesses. Modify your code such that the player is able to indicate the number of hidden digits, between 1 and 7, and the maximum number of gusses, between 1 and 100. Note: Make sure that your program has no compile-time error/warning before submission. If your submitted program can't be compiled, you will lose the major part of the mark. Also, after successfully compiling your program, test it with various inputs and make sure about any types of fatal/non-fatal run-time errors. The prototypes of the custom functions you should implement are: * This function receives an array of integers, size of the array, and an integer, value. * If value is found inside the array, it returns 1, and otherwise it returns -1. This function * will be called from the next function, uniqueRand. int found(int al], int size, int value); * This function receives an array of integers, and its size. * Then it generates random unique digits and stores them into the array. int uniqueRand(int all, int size);

we then need the player to enter their guess. After every guess we have to give an output of how many numbers they have in the right location
and how many they have the right number. The player will keep guessing until their 10 tries are over. Then we ask them if they want
to play again*/

THIS IS MY CODE I JUST NEED HELP WITH THE FUCTIONS AND THE SECOND MODIFICATION THAT HAS TO BE DONE THANK YOU

also if you can look through the rest of my original code and make sure you make adjustments to the functions you added so the correct messages are printed

hey thank you soo much for your help but please make sure you use my original code to make the two adjustments. The changes have to be made around my original code
