Pointer Arithmetic and Types of Pointers

Pointers are a fundamental concept in programming languages like C and C++, providing a powerful way to interact with memory. They allow us to access and manipulate data indirectly by storing memory addresses. To understand pointer manipulation, we first need to understand the deeper meaning of pointer arithmetic. In this lesson, we’ll explore the concept of pointers, their connection with memory, and their application in pointing toward the memory of different types, like readable and writable memories. To explain this connection, we’ll explore the four types of basic pointers, each with its own characteristics and examples. So, let’s dive in!

Pointer arithmetic

Pointer arithmetic refers to the mathematical operations performed on pointers, which allows us to navigate through memory efficiently. Pointer arithmetic is an essential aspect of working with arrays, data structures, and dynamic memory allocation. Here’s an in-depth explanation of pointer arithmetic.
