Everything that I have

The most interesting feature in C++ is the ability to implement the Object Programming Concept. Well here I wont go into the theory of OOP or what are its details, I want to give an example of how to use class, how to create an object and how to invoke methods.

What are objects, object represent real life object, like a person. Well each person has different names say Mr. X, Mr. Y etc., but they all have some property that can be define by a class. We can define age, gender, name, address, etc for all. so such definition is a class. Lets take the following example:

#include<iostream>
 
using namespace std;
 
class Person        //Defining the class Person
{
       int age;
       char name[20], address[20];
       public:
           void getInfo();      //public member methods
           void putInfo();
};
 
//defining method 
void Person::getInfo()
{
       cout << "Enter your age: ";
       cin >> age;
       cout << "Enter Name: ";
       cin >> name;
       cout << "Enter Addres: ";
       cin >> address;
}
void Person::putInfo()
{
      cout << "Name: " << name << endl;
      cout << "Address: " << address << endl;
      cout << "Age: " << age << endl;
}
int main()
{
      Person A, B;       //Creating two object of class Person 
      A.getInfo();       // Accessing the methods
      B.getInfo();
 
      A.putInfo();
      B.putInfo();
 
      return 0;
}

From the above example we have defined a class Person which contain attribute age, name and address, then two public function (methods) are defined. Then from the main function, two object A and B are created which then access the methods using the dot operator. If you have question, spell it out in the comments thanks.
