functions in kotlin

In Kotlin there are local functions that can be defined within a larger function. These functions are only visible within this larger function and cannot be accessed from outside. Local functions have the advantage of making code more readable and clear by packaging complex subtasks within a larger function. This can also help avoid code duplication and increase code maintainability

Single-line functions (also known as one-expression functions) in Kotlin are functions that consist of only one expression and are defined without curly brackets {}. They help improve the readability and compactness of the code, especially for simple and short functions. The syntax of a Single Expression Function in Kotlin has the following structure: fun – The keyword to define a function. functionName – The name of the function.

In Kotlin, the return statement ends the execution of a function and returns a value, if any, to the caller. Here is an example of using the return statement: When a function uses the return statement to return a value, the return type of the function must be explicitly specified. The return type is defined after the list of parameters and the colon. In the example above, the return type was Int

A function is a part of a program that performs a specific task or calculation and, if necessary, returns a result. Functions are used to divide the code into logical units, which allows the code to be reusable and clear. In other words, a function can be viewed as a type of "subprogram" that performs specific tasks within a larger program and sends the result of those tasks to the
