#include <stdio.h> int main() { int num1, num2, *x, *y, sum; printf("Enter two integers to add\n"); scanf("%d%d", &num1, &num2); x = &num1; y= &num2;
sum = *x + *y; printf("The Sum of the numbers = %d\n", sum); return 0; } |
Output
Enter two integers to add

#include <iostream> using namespace std; int main() { int num1, num2; int *pointer_1,* pointer_2; int sum; cout<<" Please Enter the first number: "<<endl; cin>>num1; cout<<" Please Enter the second number: "<<endl; cin>>num2; pointer_1 = &num1; //assigning an address to pointer pointer_2 = &num2; sum = *pointer_1 + * pointer_2; //values at address stored by pointer cout<<"The Sum is: "<< sum<<endl; return 0; } |
Output
Please Enter the first number:
3
Please Enter the second number:
4
The sum is: 7
