go lang與c/c++的連結樣本：

foo.hpp

//foo.hpp#ifndef _FOO_HPP_#define _FOO_HPP_template<typename T>T add(const T& lhs,const T& rhs){return lhs+rhs;}void display();#endif //_FOO_HPP_

foo.cpp

//foo.cpp#include "foo.hpp"#include <iostream>void display(){std::cout<<"this message is from foo.cpp -display"<<std::endl;}

foo_wrap.h
