Difference between two numbers using function in C++

---

This code calculates the difference between two integers using the diff function and outputs the result using cout. The diff function takes two integers as input (num1 and num2) and returns their difference (num3). The main function calls the diff function with the values 1 and 99 as input, and outputs the returned value using cout.

Source Code

#include<iostream>
using namespace std;
int diff(int num1, int num2)
{
    int num3=num2-num1;
    return num3;
}
int main()
{
    cout<<diff(1,99);
    return 0;
}
