Object in C++


Object is a blue print of class. That control the behavior of the class and store the data of class. In a C++ object create in the main function of the class to call the data member and member function and control the behavior of the class by calling function of class. In a single program we can create multiple object of  a single class.

Object is an instance of class and it it is created at runtime so, we can say object is a runtime entity

 simple program of Object

#include <iostream.h>
#include <conio.h>

 Class simple           //Classs keyword and class name
{                                
Public:                          // access specifier                      
Void display()             //Class function
        {
            
             Cout<<”hello world”;
         }
};                                
Void main()            //main function
{
simple  s1;                  //create an object (s1)
s1.display()                 //calling of Class function by object
}

in this program we create a class that name is simple
and in this class we create a Class function display() 

To call class and it function we create main function() 

In this main function we create object that name is  s1.The object s1 use to call the class function to print the ("hello world")
