Add two Numbers using Pointer in C++
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 data 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.
C++ Programming Code to Add Two Numbers using Pointer
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 num1, num2, *ptr1, *ptr2, sum=0;
cout<<"Enter the two number :";
cin>>num1>>num2;
ptr1 = &num1;
ptr2 = &num2;
sum = *ptr1 + *ptr2;
cout<<"Sum of the two number is "<<sum;
getch();
}
When the above C++ program is compile and executed, it will produce the following result:
Here we initialize the address of first number to first pointer and the address of second number to second pointer.
Now using value at address operator (*), we add the two number and initialize to sum and print the added number on the screen.
