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 were provided with a variable that stored a number and you were asked to check if the number lies between **8** and **75**, inclusive of **8**.

In other words, `check` **>= 8** and `check` **< 75**.

## Solution

Let's look at how we should go about this.

* The first thing was to make sure `check` was less than **75**.

```
check < 75
```

* Next, we had to make sure that `check` was also greater than or equal to **8**.

```
check >= 8
```

* The last step is simply combining both conditions using the `&&` operator.

```
check < 75 && check >= 8
```

You can find the complete solution below:

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