The class declaration goes into the header file. It is important that you add the #ifndef
include guards. Most compilers now also support #pragma once
. Also I have omitted the private, by default C++ class members are private.
// A2DD.h #ifndef A2DD_H #define A2DD_H class A2DD { int gx; int gy; public: A2DD(int x,int y); int getSum(); }; #endif
and the implementation goes in the CPP file:
// A2DD.cpp #include "A2DD.h" A2DD::A2DD(int x,int y) { gx = x; gy = y; } int A2DD::getSum() { return gx + gy; }
