Addition of two numbers using call by reference in C++
#include <iostream>
using namespace std;
//function prototype
int add(int *num1, int *num2);
int main()
{
int num1,num2,sum;
//Two numbers from the users will be taken
cout<<"Enter your first number: "<<endl;
cin>>num1;
cout<<"Enter your second number: "<<endl;
cin>>num2;
//Sum to store values from the functions
sum = add(&num1,&num2);
cout<<"The sum of two numbers are: "<<sum;
return 0;
}
//add function definations
int add(int *num1, int *num2)
{
int result = *num1 + *num2;
return result;
}Output
Enter your first number:
5
Enter your second number:
4
The sum of two numbers are: 9
