I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.

#include <iostream>
using namespace std;
 
int main() {
 
    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;
 
    return 0;
 
}

Result:

Enter the two number :10

20

Sum of the two number is 30
