Question

Write a C++ program to do the following:

Define a function called "difference" that can accept two integer values as arguments and returns an integer (which is the obtained by subtracting the first the second argument from the first argument.

Declare two variables in the main function and assign them values 7 and 10.

Call the difference function with the above created variables as arguments. Print the returned difference in the main function.

Call the function again with 11 and 5 as arguments and print the obtained difference.

#include <iostream>

using namespace std;

int difference(int, int);

// main function

int main(){

// define some variable here

int first, second, result;

//assign value

first = 7;

second = 10;

// call difference function and get result

result = difference(first,second);

// print first result here

cout << "Differences between "<< first <<" and " << second <<" is : " << result;

//assign value again

first = 11;

second = 5;

// call difference function again and get result

result = difference(first,second);

// print second result here

cout << " Differences between "<< first <<" and " << second <<" is : " << result;

return 0;

}

// define difference function

int difference(int first, int second){

// subtracting and return value

return first - second;

}

Output:-

Differences between 7 and 10 is : -3

Differences between 11 and 5 is : 6
