1. Does a program run faster when the programmer leaves optional parameters out of a subroutine call? Why or why not?
2. Why do you suppose that variable-length argument lists are so seldom supported by high-level programming languages?
3. In Section 7.2.2 we introduced the notion of a generic reference type (called void * in C) that refers to an object of unknown type. Using such references, implement a “poor man’s generic queue” in C, as suggested at the beginning of Section 8.4. Where do you need type casts? Why? Give an example
of a use of the queue that will fail catastrophically at run time, due to the lack of type checking.
