Unlike standard variables, performing math on a pointer alters the memory address it references. Kanetkar illustrates how adding or subtracting integers from a pointer depends entirely on the data type it points to (e.g., how scaling works differently for a 1-byte char versus a 4-byte int ). 3. Arrays and Pointers Before diving into the book, it’s essential to
by Yashavant Kanetkar is a definitive resource for mastering one of the most powerful yet challenging features of the C programming language. Kanetkar’s clear, conversational tone and step-by-step progression make complex memory management concepts accessible to both students and early-career programmers. Why This Book is Essential
