Meaning – The term parameter, refers to a variable that is given a constant value for a specified application and that may denote the application.
It also refers to data passed to a program or procedure by a user or another program, namely as an operand in a language statement, as an item in a menu, or as a shared data structure.
In computer programming, a parameter or “argument” is a value that is passed into a function. Most modern programming languages allow functions to have multiple parameters.
When a function has input parameters, the output of the function is often affected by the values that are passed into the function. Therefore, a single function can be called multiple times within a program and produce different outputs each time.
Example of usage – “In computer programming, two notions of parameter are commonly used, and are referred to as parameters and arguments—or more formally as a formal parameter and an actual parameter.”
