In the example, which statement correctly identifies the parameter and the argument?

• A. Parameter is speed; Argument is 5 or 2
• B. Parameter is number; Argument is 5 or 2
• C. Parameter is speed; Argument is number
• D. Parameter is 5; Argument is speed

Answer: (A)

In programming, a parameter is the name used in a function definition as a placeholder for a value, while an argument is the actual value supplied when the function is called. In the example, speed is the parameter because it’s the named input the function expects. The numbers 5 and 2 are the arguments because they are the concrete values passed to the function when it runs. This fits the idea that parameters are identifiers in the function design, and arguments are the specific values provided at call time. The other statements mix up these roles—treating a numeric value as the parameter name or treating the word speed as the value being passed doesn’t align with how parameters and arguments are defined.
