Question

question: 4
what is the difference between calling and defining a function?

• calling a function is when you give a function a name.

defining a function is when you determine what is inside that function.

• calling a function is when you determine what a function does.

defining a function is when you want to use a called function in your program.

• defining a function is when you determine what a function does.

calling a function is when you want to use a defined function in your program.

• calling and defining a function are two ways to describe the same thing - when you call or define a function, you are using a function in your program.

Explanation:

To solve this, we analyze each option:

• Option 1: Giving a function a name is part of defining (or declaring) a function, not calling. So this is incorrect.
• Option 2: Determining what a function does is defining, and using a function is calling. This swaps the two, so it's incorrect.
• Option 3: Defining a function involves specifying what the function does (its code/behavior), and calling a function is using that defined function in the program. This matches the correct concepts.
• Option 4: Calling and defining are distinct actions, not the same. Defining sets up the function, calling uses it. So this is incorrect.

Answer:

C. Defining a function is when you determine what a function does. Calling a function is when you want to use a defined function in your program.
