How to avoid nested ifs in C?

I have this code here in C and I want expCompare to have no nested ifs. I would like to ask if there is any other way except this?

typedef struct expo Exponent;
struct expo {
    char tag;
    int ex;
    int ey;
    int ez;
};

int expCompare(Exponent alpha, Exponent beta) {
    if (alpha.ex > beta.ex) {
        return 1;
    } else if (alpha.ex == beta.ex) {
        if (alpha.ey > beta.ey) {
            return 1;
        } else if (alpha.ey == beta.ey) {
            if (alpha.ez > beta.ez) {
                return 1;
            } else if (alpha.ez == beta.ez){
                return 0;
            } else {
                return -1;
            }
        } else {
            return -1;
        }
    } else {
        return -1;
    }
}
