Hi, I'm just learning how to program in C. When I try to compile my program, I get errors saying that NULL is undeclared. I didn't think I had to declare it...
So anyway, can anyone tell me how I go about declaring it? Thanks.

Thread 'Microsoft Technical Interview question'

I was not able to figure this out during the interview, but I have been look in this all weekend and I read something online that said it can be done at O(N) using something called the counting sort histogram algorithm ( I did not learn that in my advanced data structures and algorithms class). I have watched some youtube...
