3. The relationship between C variables, types, and assignment is:

		C variables are untyped, and assignments to variables can be of any type.
		C variables are declared with a type, and the initial assignment must be compatible with that type, but future assignments can be of any type.
		C variables are typed and immutable, and no assignments can be made to a variable once it is initialized.
		C variables are declared with a type, and every assignment to a variable must be compatible with that type.

4. Which of the following are valid scope lifetimes for C variables?

		Static scope, with a lifetime the same as the program
		Module scope, with a lifetime the same as the module they are in.
		Global scope, with a lifetime the same as the program
		Block scope, with a lifetime from where they are declared to the nearest closing curly brace.

5. Given a pointer to a region of memory allocated by malloc(), how can the programmer find out how much memory was requested at allocation time?
