Pointers

In this chapter, we explain pointers. Pointers are the heart of C programming. It is especially very important for hardware programming engineers. To be able to use the pointers efficiently, it is essential to have basic knowledge of digital concepts, such as bit, byte, register, memory address, hexadecimal numbers, register content, 2’s complement, signed and unsigned numbers, etc. We advise the reader to study Chap. 1 before proceeding with this chapter.
