What isparameter

In computer programming, parameters refer to any data that is supplied to a program by the user or another program to configure it for a specific function. This data can take many different forms, such as file names, coordinates, sets of numbers, monetary values, or specific types of code.

In some instances, parameters may be necessary for a program to function correctly, while in others they may be optional. When a program is loaded, parameters are often entered as a list of values following the program name.

For example, in the command “dir /p” in DOS, the parameter switch /p tells the program to pause after displaying each screenful. Parameter-driven software relies heavily on parameters to customize the program’s behavior.

FAQs about Parameters in Computer Programming:

What is the importance of parameters in programming?

Parameters are important because they allow programmers to customize a program’s behavior and make it more versatile. By using different parameters in different situations, a program can perform a wide range of functions.

What types of data can be used as parameters?

Any type of data can be used as a parameter, including numbers, text, file names, and more. The type of data used as a parameter will depend on the specific needs of the program and the task it is performing.

How are parameters passed to a program?

Parameters are typically passed to a program as a list of values following the program’s name. The program can then use these values to configure its behavior and perform specific tasks.


Parameters are a crucial aspect of computer programming, allowing developers to customize a program’s behavior for a specific function. By understanding how parameters work, programmers can create more versatile and efficient software.
