What is the difference between defining and calling a function?

Defining a function means you are teaching the computer a new word. Calling a function means you are commanding the computer to complete defined actions.

There is no difference.

Calling a function means you are teaching the computer a new word. Defining a function means you are commanding the computer to complete defined actions.

Defining a function must be done each time you want to use the function. Calling a function can only happen once in your code.

Which of the following is NOT a purpose of using functions?

Functions let Tracy do new things.

Functions help group statements together to make your code more readable.

Functions let you execute code a fixed number of times.

Functions allow the programmer to reuse code.

Suppose you write a function. How many times can you call the function in your code?

Once

Not more than the number of commands the function holds

As many times as you want

What is the difference between a binary operator and a unary operator?
