Single class has a Class Redefinition Error

Question

I\'m new to C++, and I\'m having a problem with my class definitions in a header file. The code for the header file (Student.h) is:

#include 
u         


        

Answer 1

I prefer using

   #pragma once

as the first line of a header file, instead of the defines. Even if this is non-standard, it does avoid name clashes and can reduce compile time.
