An array argument performs multiple calculations on one or more sets of values and then returns either a single value or multiple values. _________________________

For a non-empty linked list, select the code that should appear in a function that adds a node to the end of the list. newPtr is a pointer to the new node to be added and lastPtr is a pointer to the current last node. Each node contains a pointer nextPtr.

a. lastPtr->nextPtr = newPtr; lastPtr = newPtr b. lastPtr = newPtr; lastPtr->nextPtr = newPtr c. newPtr->nextPtr = lastPtr; lastPtr = newPtr d. lastPtr = newPtr; newPtr->nextPtr = lastPtr

________ buffering maintains two screen buffers—one for display purposes (the on-screen buffer) and the other for drawing purposes (the off-screen buffer).

a) Duet. b) Double. c) Fast. d) None of the above.
