Learn the syntax, data types, and operations essential for programming in Scala

Become a Scala Developer

In this module, we will learn Scala from the ground up. This module aims to teach us how to write basic programs, assuming we have no prior knowledge of the language. We will start with a brief introduction to Scala to understand its functionality and applications. We will then move discuss the key features and functions of the language (data types, functions, classes, etc.) in detail. In the end, we will have all the basic knowledge of how to program in Scala.

## Task

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


## Solution

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. 

```
print(f(x,y))
```

You can find the complete solution below:

>You were required to write the code on **line 2**.
