STEP 1

How it works.

In the brackets of the function, specify the input numbers. return gives the result to the code.

int add(int a, int b) {
    return a + b;
}

✦ add(2, 3) will return 5.

STEP 2

add(2, 3) will return 5.

cout << add(2, 3) << endl;

✦ Compare this to the first one. Then do the cool job yourself.

IN-CLASS PRACTICE

Manually type the program from the sample. So you'll remember commands and brackets.

#include <iostream>
using namespace std;

int add(int a, int b) {
    return a + b;
}

int main() {
    cout << add(2, 3) << endl;
    return 0;
}

HOMEWORK

Create a function int multiply (Zint a, int b), which returns the work. From main output multiply(3, 4).
