写代码娱乐一下下：
//函数实现加法 http://write.blog.csdn.net/sunboyiris int add(int i,int j) { return i+j; } //命名空间实现加法 http://write.blog.csdn.net/sunboyiris namespace fun1{ int add(int i,int j) { return i+j; } } //模板实现加法 http://write.blog.csdn.net/sunboyiris template<typename T> T add1(T i1,T j1) { return i1+j1; } //类实现加法 http://write.blog.csdn.net/sunboyiris class class_add { public: int add2(int x,int y) { return x+y; } }; //结构体实现加法 http://write.blog.csdn.net/sunboyiris struct struct_add { int add2(int x,int y) { return x+y; } }; //内联汇编实现加法 http://write.blog.csdn.net/sunboyiris int add4(int x,int y){ int i1; _asm{ mov eax ,x add eax ,y mov i1,eax } return i1; } //位运算实现加法 http://write.blog.csdn.net/sunboyiris int add3(int a, int b){ int temp = 0; do{ temp = a; a = a & b; b = b ^ temp; a = a << 1; }while(a != 0); return b; } //调用形式如下： cout<<add(2,3)<<endl; cout<<fun1::add(2,4)<<endl; cout<<add1(1.2,1.3)<<endl; cout<<a.add2(12,34)<<endl; cout<<b.add2(12,45)<<endl; cout<<add4(12,35)<<endl;
