Syöttöargumentteja

Syöttöargumentteja, known in English as input arguments, are values or data that are passed to a function or program when it is executed. These arguments allow the user to customize the behavior or provide specific information that the function needs to perform its task. Think of them as instructions or data that you give to a tool so it knows what to do and how to do it.

In programming, functions are designed to be reusable blocks of code. To make them flexible, they accept syöttöargumentteja. For example, a function designed to calculate the area of a rectangle might require two syöttöargumentteja: the length and the width. Without these arguments, the function wouldn't know the dimensions of the rectangle to calculate its area.

The way syöttöargumentteja are passed can vary. They can be positional, meaning their order matters, or they can be named, where the argument is identified by a label. Some functions can also accept optional arguments, which are not required for the function to run but can modify its output or behavior. The number and type of syöttöargumentteja are defined by the function's signature. Understanding and correctly using syöttöargumentteja is fundamental to effectively utilizing and programming software.
