Answer 1

1.

a. false: Void functions do not return a value after the function executes

b. false: Parameters are the names of the information that we want to use in a function or procedure. The values passed in are called arguments.

c. false: A function cannot be defined inside the another function, but a function can be called inside a another function, because after returning a value the control is given back to calling function.

d. true: You're passing the parameter as an IN parameter - that means you can't change it, which if you think about it, makes sense. It's a constant, in effect.
