For example,if i were to compile and run this code,it would work perfectly.My question is,how exactly does it work.How does the compiler divide, for example the hex number AF3F6F9F with the number 2 and give out a result that is satisfactory?

Here's an example program:

```
#include <stdio.h> 
int main(void)
{
    int a, b, c, d, e, f;
    printf("Insert MAC address in hex form: ");
    scanf("%x:%x:%x:%x:%x:%x", &a, &b, &c, &d, &e, &f);
    if ((a == 0xff) && (b == 0xff) && (c == 0xff) && (d == 0xff) && (e == 0xff) && (f == 0xff))
    {
        printf("This is a broadcast address\n");
    }
    else if ((a % 2) == 0) { printf("This is a unicast address\n"); }
    else if ((a % 2) != 0)
    {
        printf("This is a multicast address\n");
    }
    return 0;
}

```
