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 ...
- mattmanser 12y agoNo, 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.
