CHAPTER 10 Pointers

‘If you don’t understand pointers, you’re not really a C programmer.’

— Brian W. Kernighan

Learning Objectives

This chapter aims to provide a fundamental understanding of pointers, their various representations and associated operations. A pointer, also known as a pointer variable, is a variable that stores the address of another variable or data item. Pointers are essential for efficient dynamic memory management, data structure manipulation and managing hardware interaction. Pointers are a powerful feature of C programming.

After completing this chapter, readers will be able to:

Understand the need for pointers
