Thread: Need help finding error

Hi there! I recently started to learn C Language.
I managed to write program for getting sum and average score for english and spanish.

But the problem is that i'm keep getting "source.c has stopped working" error.

This is the program that i wrote

Code:

#include <stdio.h>

FILE *file;


void main(void)
{
    int num[10], spa[10], eng[10], a, sum[10], avg[10];
    char name[10];


    printf("Stud # Name Spanish English Sum Average\n");


    file = fopen("Data.txt", "r");
    for (a = 0; a < 10; a++)
    {
        fscanf(file, "%d %s %d %d", &num[a], &name[a], &spa[a], &eng[a]);
        sum[a] = spa[a] + eng[a];
        avg[a] = sum[a] / 2;
        printf("%d %s %d %d %d %d", num[a], name[a], spa[a], eng[a], sum[a], avg[a]);
    }
    fclose(file);
}

And this is the "Data. txt"

Code:

1111 Guy1 82 91
1112 Guy2 75 29
1113 Guy3 88 75
1114 Guy4 50 62
1115 Guy5 70 56
1116 Guy6 96 98
1117 Guy7 75 90
1118 Guy8 88 82
1119 Guy9 82 88
1120 Guy10 91 99

As far as i know, this program can open "data.txt" but can go further than that.

Thanks in advance!

As far as i know, this program can open "data.txt" but can go further than that.

How do you know that since you never check that the file opened successfully? By the way why the global variable for that FILE*? You should avoid global variables whenever possible.

Also your program doesn't even compile for me and you really should be getting at least one warning that you need to fix.

main.c|6|error: return type of ‘main’ is not ‘int’ [-Wmain]|
main.c||In function ‘main’:|
main.c|21|warning: format ‘%s’ expects argument of type ‘char *’, but argument 3 has type ‘int’ [-Wformat=]|
||=== Build failed: 1 error(s), 1 warning(s) (0 minute(s), 0 second(s)) ===|

If you're not getting any warnings you should see about increasing your compiler warning level. If you are getting some warnings, don't ignore the warnings, fix them.
