Kotlin Syntax

In the previous chapter, we created a Kotlin file called Main.kt, and we used the following code to print "Hello World" to the screen:

Example:

fun main()

{

println("Hello World")

}

Ex Explained:

The fun keyword is used to declare a function. A function is a block of code designed to perform a particular task. In the example above, it declares the main() function.

The main() function is something you will see in every Kotlin program. This function is used to execute code. Any code inside the main() function's curly brackets {} will be executed.

For example, the println() function is inside the main() function, meaning that this will be executed. The println() function is used to output/print text, and in our example it will output "Hello World".

Note: In Kotlin, code statements do not have to end with a semicolon (;) (which is often required for other programming languages, such as Java, C++, C#, etc.).
