Functions
A function is a reusable piece of code. For example you can create a function that calculates the average of given numbers, a function that prints out a string, or a function to retrieve information from a web page. One thing to keep in mind when creating a function is that the function should only have one job.
Here is an example of a function in C++ :
int sum(int a, int b) {
return a + b;
}
This functions takes two integers as the argument and returns a single integer which is the sum. You can use it like this.
int main() {
std::cout << sum(5, 8) << std::endl; // Prints out 13.
}
Your task is to create the function called product which accepts two integers and return a single integer which is the product of the inputs.
Note: you should not write the main function. The test cases will define their own main function.
#include <iostream>
int main() {
std::cout << product(5, 8) << std::endl;
}
