Parameter describes

Parameter describes

• A. A local variable inside a function
• B. An extra piece of information passed to a function to customize it for a specific need
• C. A type of array element
• D. An error message

Answer: (B)

Parameters are the inputs a function uses to perform its task. They act as placeholders in the function definition, letting the same function work with different values. When you call the function, you provide actual values called arguments, which customize the function’s behavior for that specific call. For example, in a function that calculates total price, you might have parameters for the base price and the tax rate. The values you pass in (the arguments) determine the exact result. That description fits best because a parameter is about supplying extra information to tailor what the function does. A local variable inside a function is just a variable declared within the function, not a parameter. An array element is a data item in an array, unrelated to how a function receives input. An error message is not a parameter at all.
