Question

C++ only

Write a program that prompts the user for three integers, find the maximum number, their summation and their difference and prints it out to the console.

The program must contain at least 3 functions:

1. A finding maximum function: The function will accept three inputs and return the maximum number.

2. A summation function: The function will accept three inputs and return the summation of all three numbers.

3. A subtraction function: The function will accept three inputs and return the subtraction of all three numbers.

Example: Enter an integer: 45

Enter another integer: 83

Enter another integer: 50

45 + 83 + 50 = 180

45 – 83 - 50 = -88

The maximum number is 83

Answer 1

#include <iostream>

using namespace std;

int summation(int n1, int n2, int n3) {
    return n1 + n2 + n3;
}

int subtraction(int n1, int n2, int n3) {
    return n1 - n2 - n3;
}

int max(int n1, int n2, int n3) {
    int num = n1;
    if (n2 > num) num = n2;
    if (n3 > num) num = n3;
    return num;
}

int main() {
    int n1, n2, n3;
    cout << "Enter an integer: ";
    cin >> n1;
    cout << "Enter another integer: ";
    cin >> n2;
    cout << "Enter another integer: ";
    cin >> n3;
    cout << n1 << " + " << n2 << " + " << n3 << summation(n1, n2, n3) << endl;
    cout << n1 << " - " << n2 << " - " << n3 << subtraction(n1, n2, n3) << endl;
    cout << "The maximum number is " << max(n1, n2, n3) << endl;
    return 0;
}
