Class:
Here we can take Human Being as a class. A class is a blueprint for any functional entity which defines its properties and its functions. Like Human Being, having body parts, and performing various actions.
Objects:
My name is Abhay, and I am an instance/object of class Male. When we say, Human Being, Male or Female, we just mean a kind, you, your friend, me we are the forms of these classes. We have a physical existence while a class is just a logical definition. We are the objects.
program-
#include
using namespace std;
//Create class
class myclass
{
public:
//data member that print hello world
int display()
{
cout<<"Hello world";
}
};
int main()
{
//create class object
myclass obj;
//call function using object.
obj.display();
return 0;
}
output-
Hello world
