Thread: Need Help with Letter Guessing Game

There's something wrong with my code. It builds no problem, and it starts up okay. But when it asks to enter a letter it gives me a Run-time check failure #3-T error. If I choose to ignore it, I could keep entering guesses, but the error keeps coming back whenever I do.

Code:

#define _CRT_SECURE_NO_WARNINGS 
#include <stdio.h>
#include <ctype.h>




#define MAXGUESSES 5












void LetterGuessRules();//This function provides instructions to user
int PlayOneGame(char solution);//This function runs one game, it returns a 0 if the game is over
char  GetGuess(); //Gets guess from player
int CompareGuessAndSoultion(char guess, char solution);//Takes two arguments, the guess from the player and the solution from the file. Returns a 1 if the guess is correct or a 0 is it's not correct
int GameCount();


int main()
{
    int i = 0;
    int numgames = 0;
    char solution;
    char guess;
    int compareletter(char guess, char solution);
    FILE *inPtr;
    inPtr = fopen("letters.txt", "r");
    fscanf(inPtr, "%c", &solution);
    solution = toupper(solution);
    LetterGuessRules();
    //# of games player wants to play
    int GameCount();
    printf("Please enter the number of games you want to play\n");
    scanf("%d", &numgames);
    for (i = 1; i <= numgames; i++)
        //display the value of game
    {
        //get letter to guess from file
        fscanf(inPtr, "%c", &solution);
        solution = toupper(solution);
        PlayOneGame(solution);
        printf("\nThe letter is %c\n", solution);
    }








    fclose(inPtr);

    void LetterGuessRules()

    printf("Welcome to the Letter guessing game\n");
    printf("\nEnter how many games you want to play(1-8 games)\n");

    return guess;
}




//Compares the guess and the solution

//returns 0 if guess & answer aren't the same

{
    if (guess == solution) //If the guess was correct
    {
        printf("Great Job!\n");
        return 1;
    }
    else
