On Secretly Terrible Engineers

The mod operator isn't the solution to that problem, but that problem shoves integer division in your face. If a dev sees that and isn't curious enough to understand there is a division operator and a remainder operator, just like when you studied fractions in 3rd grade, I don't know that I want to work with that person.

And every dev should have hit the remainder operator at bare minimum when they had a long running loop and wanted to print a status every kth operation, eg

   for(int i=0; i < 100000000; i++){
     // some operation
     if(i % 100000 == 0)
       printf("** operating on count %d\n", i);
   }

or when processing a big file, printing every k lines; or when running a slow operation, printing every k seconds; or ...

No, because for most of those problems there's an easy alternative, declare another counter variable and you can just go:

    z++;
    if(z>100000) {
        print x;
        z=0;
    }

When I was taught maths there was no emphasis on remainders and it certainly wasn't denoted with a % sign. I vaguely remember writing something like 12r3 in primary school. The r meaning remainder.
