Funktiokutsulla refers to the act of invoking or executing a function within a computer program. When a function is called, the program's control flow transfers to the specified function. This allows for code reusability and modularity, as a block of code can be defined once and then executed multiple times from different parts of the program.

During a function call, arguments can be passed to the function, providing it with the data it needs to perform its task. These arguments are received by the function as parameters. Once the function completes its execution, it can optionally return a value back to the part of the program that called it. The process of returning a value is crucial for functions that are designed to compute or retrieve information.

The concept of a function call is fundamental to most programming paradigms. It enables the breakdown of complex problems into smaller, manageable subroutines. This organization leads to more readable, maintainable, and testable code. Without function calls, programs would likely consist of long, monolithic blocks of instructions, making them difficult to understand and debug. The efficiency and structure provided by function calls are essential for modern software development.
