More than one answer may be true. What are three commands that use Regular Expressions - give a nontrivial example of each command. The best answer is C, but A is also acceptable since we discussed that in class.
Object oriented programming involves the partitioning of a program into classes and methods.
A class and its subclasses specify a hierarchy of objects, which are operated on by the methods. If an erroneous command, state that. Give one example. Variables in any programming language are used to represent abstractions or more complex structures. In makefiles, variables store information that might, for example, be a long pathname to a directory or file.
