C++ initial value of reference to non-const must be an lvalue

Question

I\'m trying to send value into function using reference pointer but it gave me a completely non-obvious error to me

#include \"stdafx.h\"
#include 

        

Answer 1

When you call test with &nKByte, the address-of operator creates a temporary value, and you can't normally have references to temporary values because they are, well, temporary.

Either do not use a reference for the argument, or better yet don't use a pointer.
