Object-oriented for C + +

Here is a header file people.h, this header file has a class people, the class has an implementation of the method SayHello ();

1 class people{23public:4     void SayHello (); 5 };

Next, the source file implements the people SayHello method for printing a sentence;

#include <iostream>"people.h"usingnamespace  std; void People::sayhello () {    cout<<"Hello world! "<<Endl;}

Finally, the main function of the file, the main new people object, and called his SayHello object to print a word; 1 #include <iostream>

1#include <iostream>2#include"people.h"3 using namespacestd;4 5 //class people{6 //7 //Public :8 //void SayHello () {9 //cout<< "Hello world!" <<endl;Ten //    } One //}; A  - intMain () { -People *p =Newpeople (); the     //call the SayHello method of the object -P->SayHello (); -  -     /*Delete objects that are not used*/ + delete p; -     return 0; +}

In fact, the object-oriented mechanism of C + + and other object-oriented programming languages, the logic is the same, but there may be some grammatical differences, that's all.
