Two ways to define C + + classes

In-class definition

Class teacher{private:string _name;int _age;public:teacher () {printf ("Create Techer \ n");} Teacher (string name) {_name = name;printf ("Create techer with name \ n");} void SetName (string name) {_name = name;} String GetName () {return _name;} void Say () {string des = "I ' m Teacher and my name is";d es + = _name;cout<< des<< endl;//printf (des);};

　　

Out-of-class definitions

Namespacedemo.hnamespace myprintspace{    void Say ();} Namespacedemo.cpp#include "namespaceDemo.h"//In order to invoke a function or variable with a namespace, precede the name of the namespace, void Myprintspace::say () {cout< < "Myprintspace say ()" <<ENDL;}
