Using only C (not c++) design the program described

General Requirements
? Write a program that reads letters from a file called"inputLet.txt".
? Your program will ask the user to enter the number of games they wish to play (1 to 4)
? This program should open an inputLet.txt file , read in one character at a time and repeat this for the number of games the user wants to play.
? the test file will contain at least 15 letters, all lowercase
? When the number of games has been played, the program will end

? A preprocessor directive must be used to define the maximum number of guesses as 5
? If the player has used up all of their guesses, a message that the game is over should be displayed along with the letter they were trying to guess.
? You must have at least 4 user defined functions as follows:

//this function provides instructions to the user on how to play the game
void Instructions( );

//this function runs one game. It for checks either 5 incorrect guesses or correct guess.
//It returns a 0 if the game is over and the player did not guess the letter, otherwise it returns 1.

int PlayGuess(char solution);

//this function prompts the player to make a guess and returns that guess
//this function is called from inside the PlayGuess( ) function described above
char GetLetter( );

//this function takes two arguments, the guess from the player
//and the solution letter from the file.
//It lets the user know if the guess comes alphabetically before or after the answer
//The function returns 1 if the guess matches the solution and returns a 0 if they do not match
int CompareLetters(char guess, char solution);

Additional Requirements:
? Use function prototypes.
? Write comments for each function that will appear in the file before each prototype and again before each function definition.
? Be sure to comment your code adequately.
? Be sure to indent properly.
? Use meaningful variable names
