Parameter's for a program are extra little pieces of information you give a program before or during it starts. Usually so it will do something different. Such as: hello.exe -PARAMETER

Answer 2

In computer programming, a parameter is a variable which takes on the meaning of a corresponding argument passed in a call to a subroutine. In the most common case, call-by-value, a parameter acts within the subroutine as a local (isolated) copy of the argument, but in other cases, e.g. call-by-reference, the argument supplied by the caller can be affected by actions within the called subroutine (as discussed in evaluation strategy).

Nearly all programming languages support subroutine parameters. The semantics for how parameters can be declared and how the arguments get passed to the parameters of subroutines are defined by the language, but the details of how this is represented in any particular computer system depends on the calling conventions of that system.

Answer 3

Parameters are things that are passed to a function so it knows what to do, like if you're calling a function, the parameters are the things that go in the () : like if I wrote a function to add two numbers.  I might make it answer = addnums(1,1)  where 1 and 1 are the numbers to be added (1+1)

Suppose that you believe that the amount of money you are going to make next month is defined by the wage you receive per hour times the amount of hours you are going to work (y = ax)(Income=wage x hours that you work). You are able to influence the amount of hours you work next month (your boss is very flexible), but you think that you will not be able to change the height of your wage (your boss is a real pain in the *** when it comes to discussing wages). Then:

    * Your wage is the parameter

    * The amount of hours you work is the variable.

    * This is of course depending on whether you think you can or cannot change your wage.

Get it? Hope that helps some...
