Object Oriented in c++

As we know C++ is an object oriented language so everything is surrounded class and object.

Class may defined in many ways like Collection of similar types of elements or we can also say class is the user defined data type

A Class may be create as following

#include<iostream>
using namespace std; 
class A
{
 public:
 int i=10;
  void display()
  {
   cout<<"i here is"<<i;
  }
};

Ojbect of the class may be created as following

   A obj;         (classname objectname;)

To run the above class we need to call from main as following

#include<iostream>
using namespace std; 
class A
{
 public:   // access specifier
 int i;
  void display()
  {
   cout<<"i here is"<<i;
  }
};
int main()
{
  A obj;
  obj.i=100;  // call the class variable with object name
  obj.display();  // call the function of A class
  return 0;
}

Above program displays the following result
