Print an exponential

Question

I'm creating a program that compares numbers with their respective exponents, and indicates which of the three is the smallest. The problem is that I wouldn't want it to perform the operation, for example:

Let's say the smallest number was $4^{8}$, so it would calculate that value, but I want it to just print "4^8" on the screen, or related things, but without doing that operation (in this case, it prints 65536).

int main()
{
    int a, b, c, smaller, x, y, z, for_a, for_b, for_c;

    printf("first value: ");
    scanf("%d", &a);
    printf("Second value: ");
    scanf("%d", &b);
    printf("Third value: ");
    scanf("%d", &c);

    printf("Value of x: ");
    scanf("%d", &x);
    printf("Value of y: ");
    scanf("%d", &y);
    printf("Value of z: ");
    scanf("%d", &z);

    for_a= pow(a, x);
    for_b= pow(b, y);
    for_c= pow(c, z);

    if (for_a< for_b && for_a < for_c){
        smaller= for_a;
    }
    else if (for_b < for_c){
        smaller = for_b;
    }
    else {
        smaller = for_c;
    }

    printf("Smaller= %d\n", smaller);

    return 0;
}
