Sign of a number

Return a number that describes the sign of n: -1 when n is negative, 1 when it is positive, and 0 when it is exactly zero.

Use if to test the cases. The order matters — handle negative and positive first, then return 0 for what is left.

Complete int sign(int n) to return -1 if n is negative, 0 if it is zero, and 1 if it is positive.

/* Return -1, 0, or 1 for the sign of n. Do not write main(). */
int sign(int n) {
    return 0;   /* change this */
}
