C++类（一）

 #include<iostream>
 #include<string>

 using namespace std;

 //找了很久，似乎都是类放在Main方法体上

 class Person
 {
     private:
         string str_name;
     public:
         Person(string str)
         {
             str_name = str;
         }
         string Speak()
         {
             return str_name;
         }
 };

 int main()
 {
     string str_myname;
     Person *p = new Person("xtyang");
     str_myname = p->Speak();
     cout<<"My name is :"<<str_myname<<endl;
     //别忘了删除实例化的类
     delete(p);
 }
