Code runs properly, but user input for # of students is ignored.

The user should be able to enter any positive number of students, the range being 1 to 50. No matter what I input, its ignored (ex. Enter 1, prompted for 50; Enter 1, prompted for 50;and so on).

I know it should be a simple fix but I don't see where I screwed up. How do I fix this?

(Note: C++, in Visual Studio 2017)
