Thread: Help with guess the letter program

Additional Requirements & Code Errors.pdf Code .pdf Instructions.pdf

I was trying to do so, however I was not able to so that was the only way I could post it which took me awhile to even do that.

Code:

Topics: printf, scanf, file input, user defined function, and conditions (if/else, switch, loops)

Instructions:
•The program will then open a file named “letters.txt” and reads one letter per game
•The letters.txt file will contain 10 randomly selected lowercase letters
•A preprocessor directive must be used to define the maximum number of guesses as 4
•The program will end after the selected number of games have been played along with the letter
they were trying to guess
•You must have the following 5 user-defined functions:

THE FIRST TWO FUNCTIONS BELOW are called from inside the main function

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

//This function runs one game.
//Input: character from the file
//function returns 1 if the user wins the game and 0 if the user loses a game
int PlayOneGame(char);

ALL FUNCTIONS BELOW are called from inside the PlayOneGame function
(above)

//This function prompts the player to make a guess and returns that guess
char GetTheLetter();

//Input: character from file and character guess from user
//Returns 1 if the guess matches the solution & returns 0 if they don’t match
int IsAWinner(char, char);

//Input:character from file and character guess from user
//Prints a message if the guess comes alphabetically before, after,
//or equal to the letter
void CompareTheLetters(char, char);


Additional Requirements:
•Use function prototypes
•Write comments for each function prototype
•Write comment for each function definition
•Place adequate comments throughout your code
•Use meaningful variable names
 
The exact errors I got: 
•   Line 29- 'win' unreferenced local variable
•   Line 65- Expected a declaration 
•   Line 66- found '{' at file scope (missing a header?)
•   Line 76- found '{' at file scope (missing a header?)
•   78- syntax error. '}'
•   86- Expected a declaration 
•   97- Expected a declaration

109.               numGuesses = numGuesses + 1;
110.         }
111. }

Ok and what do I do to fix my errors that I received? Also where should this part be
//Input: character from file and character guess from user
//Returns 1 if the guess matches the solution & returns 0 if they don’t match
int IsAWinner(char, char);
