Inputváltozók

Inputváltozók, or input variables, are fundamental concepts in programming and data processing. They represent values that are provided to a program, function, or algorithm from an external source. These sources can vary widely, including user input from a keyboard or interface, data read from files, network requests, or sensor readings.

The purpose of input variables is to allow for dynamic and flexible operations. Instead of a program being hardcoded with specific values, input variables enable it to adapt to different situations and data sets. This makes software more versatile and reusable. For example, a calculation program can accept different numbers as input variables to perform various computations without needing to be rewritten for each new calculation.

When working with input variables, it's crucial to consider their data type, such as integers, floating-point numbers, strings, or booleans. The program must be designed to correctly interpret and process these different types. Error handling is also a key aspect, as invalid or unexpected input can lead to program errors or incorrect results. Therefore, robust programs often include validation steps to ensure that input variables meet the expected criteria before they are used. Ultimately, input variables are the bridge between the external world and the internal logic of a computational process.
