          • In this chapter, you will learn:
             – To be able to use pointers.
             – To be able to use pointers to pass arguments to 
               functions using call by reference.
             – To understand the close relationships among pointers, 
               arrays and strings.
             – To understand the use of pointers to functions.
             – To be able to define and use arrays of strings.
                                                                      4
                          7.1    Introduction
          • Pointers 
             – Powerful, but difficult to master
             – Simulate call-by-reference 
             – Close relationship with arrays and strings
             – Mostly used in Data Structures
             – Mostly used for dynamic memory allocation
