Beginning C for Arduino: Learn C Programming for the Arduino and Compatible Microcontrollers

CHAPTER 9

Using Pointers Effectively

This chapter is a continuation of Chapter 8. In that chapter, you learned what a pointer is and how to manipulate them in expressions. In this chapter, you will learn:

• Valid pointer operations
• Pointer arithmetic
• Using pointers to functions
• The Right-Left Rule for deciphering complex data definitions
• Why using pointers can lead to more efficient code

When you have finished this chapter, you should be quite comfortable using pointers in your code.

Relational Operations and Test for Equality Using Pointers

Some C expressions make sense with almost any data type...with the exception of pointers. A partial ...
