Which term describes inputs to procedures or functions?

• A. Local variables
• B. Parameters
• C. Global variables
• D. Library routines

Answer: (B)

The inputs to procedures or functions are called parameters. They act as placeholders in the function’s definition that describe what inputs the function needs. When you call the function, you provide actual values—arguments—that fill those placeholders and let the function perform its task. For example, a function defined as taking two inputs might have parameters for those values; you would supply the real numbers when you call it. Local variables are created inside the function to hold data during execution and aren’t the inputs from outside. Global variables exist outside the function and are accessible globally, not specifically the inputs to a particular procedure. Library routines are prewritten blocks of code you can use, not the inputs to your own function.
