Pointer To Object  In C++

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.

Syntax:

class name *object name;

Example:

BCA *p;

Program:

#include<iostream.h>

#include<conio.h>

class BCA

{

char name[30];

int phone no;

public:

void inputdata();

void outputdata();

};

void BCA::inputdata()

{

cout<<”input name “<<endl;

 cin>>name;

cout<<”input phone no”<<endl;

cin>>phone no;

}

void BCA::outputdata()

{

cout<<name<<endl;

cout<<phone no<<endl;

}

void main()

{

BCA *p;

p->inputdata();

p->outputdata();

getch();

}

Output:

Input name Pramod

Input phone 1234567889
