What is Functions?

A function is a unit of code that performs a special task. In programming, the function is used to break the code into smaller modules which makes the program more manageable....

Example of a Function

For example: If we have to compute the sum of two numbers then define a fun sum()....

Types of Functions in Kotlin

In Kotlin, there are two types of functions:...

1. Kotlin User-Defined Function

A function that is defined by the user is called a user-defined function. As we know, to divide a large program into small modules we need to define function. Each defined function has its own properties like the name of the function, return type of a function, number of parameters passed to the function, etc....

2. Kotlin Standard Library Function

In Kotlin, there are different numbers of built-in functions already defined in the standard library and available for use. We can call them by passing arguments according to requirements. In the below program, we will use built-in functions arrayOf(), sum() and println(). The function arrayOf() requires some arguments like integers, double, etc to create an array and we can find the sum of all elements using sum() which does not require any argument....
