Thread: Random Number Guessing Game

Code:

#include <conio.h>
#include <time.h>
#include <stdlib.h>
#include <stdio.h>
#define MAX 100


int GetGuess();
void random();
int play(int guess1, int answer1);
int compare(int guess1, int answer1);


int guess1;
int answer1;


int main()
{
    int answer;
    random();
    FILE *inptr;
    inptr = fopen("File1.txt","r");
    answer1 = fscanf(inptr,"%d", &answer);
    play(guess1,answer1);
    getch();
}
int play(int guess1, int answer1)
{
    guess1 = GetGuess();
    compare(guess1, answer1);
    
}


int GetGuess ()
{
    int guess;
    printf("Enter your guess:\n");
    scanf("%d",&guess);
    return guess;
}


int compare(int guess1, int answer1)
{
    if (answer1 == guess1)
    {
        printf("Congratulations you are a lucky winner\n");
    }
    else
    {
        printf("not working");
    }
    


}


void random()
{
    //declare variables
    int i;
    int num;
    FILE *bzvz;
    //open file to save numbers
    bzvz=fopen("File1.txt","w");
    srand(time(NULL));//seeds the number generator to randomize
    //for(i=0;i<20;i++)
    //{
        num = rand()%MAX +1;//calculates a random number from 1 and 10
        fprintf(bzvz,"%d ",num);
    //}
    fclose(bzvz);
}

I am completely stuck when assigning values to and passing variables around. It seems that the problem occurs with fscanf function. I have also guessed that it might be passing and reading it as a character, even though I said it will be an integer, and tried atoi() with no luck. I troubleshooted the error as I tried to print the given values after I assign it, with no luck. I am doing this for a friend I have recently been programming django, so I am completely out of the loop when it comes to C. Can someone please help me diagnose or point me to where I am assigning converting passing in a wrong way?

Thank you.

answer1 is the success/failure status of the fscanf call.
Since you're trying to read one thing, possible values for answer1 are 1, 0 or EOF

answer (only if answer1 == 1) is the number read from the file.
You probably want to use this number to play.
