Thread: Help with fprintf function

Hello Everybody.

The purpose for my code is to print some random code to a file but it's not.
Here's the code:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <string.h>


int main()
{
    int keyUPPER=0, keyLOWER=0, keyINT=0, i=0, j=0;
    char access[78];
    char code1[10], code2[11];
	FILE *read, *exec;


	exec = fopen("key.txt", "w");


    printf("Your access code for today is: ");
    srand((int)time(0));


    for (i=0; i<26; i++){
        keyUPPER = ((rand()%25) + 65);
        access[i] = keyUPPER;
    }
    for (i=i; i<52; i++){
        keyINT = (rand()%8) + 49;
        access[i] = keyINT;
    }
    for (i=i; i<78; i++){
        keyLOWER = ((rand()%25) + 97);
        access[i] = keyLOWER;
    }


    for (i=0; i<10; i++){
		j = rand()%78;
        printf("%c", access[j]);
        fprintf(exec, "%c", access[j]);
    }
    printf("\n");




    return 0;
}

Thanks in advance.

Thanks for the response.
I'm using VS 2010 and every time I run it I just get a blank file. Is there anything special I need to do?

Nevermind. Got it to work now. I forgot to take out an extra part of the code that I didn't post here, so now it works.

Thanks though for the response.

well i use pelles c ide for c code, and it works for me. BUT i do get the following

(8): warning #2117: Old-style function definition for 'main'.
