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.

Select the correct output for the following code:

```
val operand1 = 7
val operand2 = 3

println(operand1 / operand2)
```


Select the correct output for the following code:
<pre><code>val operand1 = 7
val operand2 = 3

println(operand1 / operand2)
</code></pre>

Select the correct output for the following code:

```
val operand1 = 's'
val operand2 = 'q'

println(operand1 <= operand2)
```

Select the correct output for the following code:
<pre><code>val operand1 = 's'
val operand2 = 'q'

println(operand1 &lt;= operand2)
</code></pre>

Select the correct output for the following code:

```
val A = true
val B = true
val exp = A || B

println(false && exp)
```

Select the correct output for the following code:
<pre><code>val A = true
val B = true
val exp = A || B

println(false &amp;&amp; exp)
</code></pre>

Select the correct output for the following code:

```
val operand1 = 7
val operand2 = 3

println(operand1 & operand2)
```

Select the correct output for the following code:
<pre><code>val operand1 = 7
val operand2 = 3

println(operand1 &amp; operand2)
</code></pre>

Select the correct output for the following code:

```
var operand1 = 7
var operand2 = 3
operand1 += operand2

println(operand1)
```

Select the correct output for the following code:
<pre><code>var operand1 = 7
var operand2 = 3
operand1 += operand2

println(operand1)
</code></pre>
