Kotlin Functions
Define functions with default, named and vararg parameters, single-expression, local, tailrec and infix functions.
Defining Function and Its Type Kotlin Program
A function is a block of code written to perform a task. A Kotlin example with source code and sample output.
Simple Function Example Kotlin Program
A function is a block of code written to perform a task. A Kotlin example with source code and sample output.
Parameterized Function Example Kotlin Program
A function is a block of code written to perform a task. A Kotlin example with source code and sample output.
Default Parameters in Kotlin
Function parameters can declare default values so callers may omit them. A Kotlin example with source code and sample output.
Named Parameters in Kotlin
Callers can pass arguments by parameter name for clarity. A Kotlin example with source code and sample output.
Vararg Parameters in Kotlin
A vararg parameter accepts zero or more values of the same type. A Kotlin example with source code and sample output.
Single Expression Functions in Kotlin
When a function body is a single expression, you can use the = syntax. A Kotlin example with source code and sample output.
Local Functions in Kotlin
A function declared inside another function is called a local function. A Kotlin example with source code and sample output.
tailrec Functions in Kotlin
tailrec marks a recursive function that calls itself as the last operation. A Kotlin example with source code and sample output.
Infix Functions in Kotlin
An infix function is called without dot notation between the receiver and argument. A Kotlin example with source code and sample output.
