Arrow Formal Parameters

As you know, if a function uses arguments, then it must declare variables that will accept the values of those arguments. These variables are called the formal parameters of the function. Aside from receiving the arguments when a function is called, formal parameters behave like any other local variables inside the function. The scope of a parameter is local to its function.

You must make sure that the formal parameters you declare are of the same type as the arguments you will pass to the function. Also, even though these variables perform the special task of receiving the values of the arguments, they can be used like any other local variable. For example, you can assign a new value to a parameter within the function.
