simple c error makes pointer from integer without a cast

manpreet Best Answer 2 years ago

I've undertaken learning c with the aid of the k & r book. Pretty exciting but I've run into trouble early on and I'm not sure how to fix the problem.

I'm trying out some really simple sample code and I'm getting the following error. I don't understand why because the code is straight out of the book.

main.c:11: warning: passing argument 2 of ‘sprintf’ makes pointer from integer without a cast


#include 

/* copy input to output; 1st version */
main() {
    int i;
    int power(int base, int n);

    for (i = 0; i < 10; i++) {
        sprintf("%d %d %d\n", i ,power(2, i), power(-3, i));
        return 0;
    }



}

int power(int base, int n) {
    int i;
    int p;

    p = 1;

    for (i = 1; i <= n; ++i)
        p = p * base;
    return p;

}

I'd appreciate a nudge to get me going on my way again.
