C++ Programming Code to Add Two Numbers using Pointer

To add two numbers using pointer in C++ Programming, you have to ask to the user to enter the two number, then make two pointer type variable of same type say *ptr1 and *ptr2 to initialize the address of both the number and make another variable say sum which contain the addition of the two number like sum = *ptr1 + *ptr2 and display the result on the screen. Here * is also called as value at address operator.

Following C++ program ask to the user to enter the two number and add the entered two number using pointer then display the addition result on the screen:

/* C++ Program - Add Two Numbers using Pointer */
		
#include<iostream.h>
#include<conio.h>
void main()
{
	clrscr();
	int number1, number2, *ptr1, *ptr2, sum=0;
	cout<<"Enter the two number :";
	cin>>number1>>number2;
	ptr1 = &number1;
	ptr2 = &number2;
	sum = *ptr1 + *ptr2;
	cout<<"Sum of the two number is "<<sum;
	getch();
}
