The word "poly" means "many" and "morph" means "form." A parameter is a limit. The way that the computer finds out which parameter is which is by the order in which your code passes the parameters into the function. It can be compared to the horsepower of an engine. parameter: In information technology, a parameter (pronounced puh-RAA-meh-tuhr , from Greek for, roughly, through measure ) is an item of information - such as a name, a number, or a selected option - that is passed to a program by a user or another program. For example, specifying parameters means defining the characteristics of something. Parameter: In computer programming, a parameter or "argument" is a value that is passed into a function . In addition, some programming languages make a distinction between arguments, which are passed in only one direction, and parameters, which can be passed back and forth, but this distinction is by no means universal. Written exams will always present algorithms and code segments using the current version of the AQA pseudo-code document, which … While the syntax of a function declaration varies between programming languages, a typical function with two parameters may look something like this: Is a variable is a parameter A, denoted by a parameter B which is also a name? since a parameter stores values, does that mean a parameter is a block in memory? In computer science, overhead is generally considered any combination of excess or indirect computation time, memory, bandwidth, or other resources that are required to attain a particular goal. The higher the horsepower, the faster the car can move.
