Output (created file) is empty...

I have a little problem,
I can get any data in the created file:
Code:
===================================

#include <stdio.h>
char candydata [999];
int findAmountOfCandyCollected( int candyCollected, int candyLost , int candyate);
int main(void)
{
int candyCollected;
int candyLost;
int candyate;

printf( "Please input the amount of candycollected : " );
scanf( "%d", &candyCollected );
printf( "Please input the amount of candylost : " );
scanf( "%d", &candyLost );
printf( "Please input the amount of candyate : " );
scanf( "%d", &candyate );
printf( "The product of your three numbers is %d\n", findAmountOfCandyCollected( candyCollected, candyLost, candyate ) );
getchar();
}
int findAmountOfCandyCollected (int candyCollected, int candyLost, int candyate)
{
return candyCollected - candyLost - candyate ;
{
int findAmountOfCandyCollected;

FILE *dataptr;
dataptr= fopen("candydata", "w");

if (dataptr !=0)
{
fprintf(dataptr, "%d ", findAmountOfCandyCollected);

}
else

{
printf("could not open the file. /n)");
}

fclose(dataptr);
return 0;
}
}

What's wrong

The problem is that your program is nonsense:

Code:

#include <stdio.h>

char candydata [999];
int findAmountOfCandyCollected( int candyCollected, int candyLost , int candyate);

int main(void)
{ 
    int candyCollected;
    int candyLost;
    int candyate;

    printf( "Please input the amount of candycollected : " );
    scanf( "%d", &candyCollected );
    printf( "Please input the amount of candylost : " );
    scanf( "%d", &candyLost );
    printf( "Please input the amount of candyate : " );
    scanf( "%d", &candyate );
    printf( "The product of your three numbers is %d\n", findAmountOfCandyCollected( candyCollected, candyLost, candyate ) );
    getchar();
}

int findAmountOfCandyCollected (int candyCollected, int candyLost, int candyate)
{
    return candyCollected - candyLost - candyate ;
    {
        int findAmountOfCandyCollected;

        FILE *dataptr;
        dataptr= fopen("candydata", "w");

        if (dataptr !=0)
        {
            fprintf(dataptr, "%d ", findAmountOfCandyCollected);
        }
        else

        {
            printf("could not open the file. /n)");
        }
        fclose(dataptr);
        return 0;
    }
}

Your main function promised to return an int, whereas it returned absolutely nothing.

Your findAmountOfCandyCollected immediately performed a return, which means that everything after that was completely ignored.

Just what the frak do you think you are trying to accomplish there?

{
    return candyCollected - candyLost - candyate ;

        }
        fclose(dataptr);

}

Then find a way to run the code after the return statement in the findAmountOfCandyCollected function.

Once you execute a return statement, you have left that function.

You can do that in 5 sec! :-)

Think about it for a moment. You want to run the rest of the code in that function, but you can't because the first line of code is a return statement. Why don't you remove the return statement?

Output (created file) is empty...
