Reading integer from file.

Hi. I am very happy to join this forum and hope that someone can help me with this little problem of mine:

I need to read a list of space-separated integers from a txt-file into my program(i.e. into an array defined by myself) for processing. Using fread() from the stdio library, I have tried doing this, but fread() seems to be able to handle char's only.

Is there something I have missed about an application of fread() for integers, or is there some other standard function or method that can help me?

Thanks in advance.

Try using fscanf(file, "%d", &value) with a text file.

Code:

---

#include <stdio.h>

int main(void)
{
    FILE *fp = fopen("input.txt", "r");
    int array[5] = { 0 };
    int i;
 
    for (i = 0; i < 5; i++) {
        fscanf(fp, "%d", &array[i]);
    }

    fclose(fp);
    return 0;
}

Thanks a lot for the answer guys, really appriciate the fast reply. Im in Shanghai, and here its past my bedtime, so I'll work with it tomorrow.

Cheers.

Remember to also check the return value of fscanf to see whether or not an integer was assigned -- if not, it might be another reason to break the loop.
