AIM: Write a C++ program to illustrate pointer to class.
THEORY:
A pointer to a C++ class is done exactly the same way as a pointer to a structure and to access members of a pointer to a class you use the member access operator -> operator, just as you do with pointers to structures. Also as with all pointers, you must initialize the pointer before using it.
SOURCE CODE:
#include<iostream>
using namespace std;
int main()
{
class man
{
public:
char name[20];
int age;
};
man m={“SUDHA”,22};
man *ptr;
ptr=&m;
cout<<“Calling through object:\n”;
cout<<m.name<<“\t”<<m.age<<endl;
cout<<“Calling through pointer:\n”;
cout<<ptr->name<<“\t”<<ptr->age<<endl;
}
OUTPUT:
Calling through object:
SUDHA 22
Calling through pointer:
SUDHA 22
