In the following lesson, we will go over the solution of the challenge: Write Your First Higher-Order Function.

We'll cover the following


In this challenge, you had to create a function which prints the result of another function.


A skeleton of the function was already provided for you. Let’s look it over.

def arithmeticPrinter(f: (Int , Int) => Int, x: Int, y: Int) = {

The function name is arithmeticPrinter and it has three parameters. The first parameter is another function f which has two parameters of its own and returns an integer. The second parameter is an integer x and the third parameter is an integer y.

You had to write a line of code which would print the result of f given that it was passed x and y as arguments.


You can find the complete solution below:

You were required to write the code on line 2.
