This will work with the original datafile:

Code:
#include <stdio.h>

int main(void)
{
        int total=0, n;
        char buf[512];
        FILE *fp;

        fgets(buf, 512, stdin);
        for(n=0; buf[n]; n++) if((buf[n] == '\n') || (buf[n] == '\r')) buf[n]=0;

        if((fp=fopen(buf, "r")) == NULL) return(1);

        while(fgets(buf, 512, fp) != NULL) if(sscanf(buf, "%d", &n) == 1) total += n;

        fclose(fp);
        printf("Total is %d\n", total);
}
