1. Introduction Pointers are one of the most powerful features of the C programming language. Pointers are variables that hold the memory address of another variable. In this tutorial, we'll explore the basics of pointers, why they are used, and how they work. 1.1. What are Pointers? A pointer is a variable that stores the memory address of another variable. Pointers allow you to manipulate data indirectly, by accessing the memory address of the data, rather than the data itself. 1.2. Why use Pointers? Pointers are used for a variety of reasons, including: Dynamic memory allocation: Pointers allow you to dynamically allocate memory at runtime, which is useful for creating data structures such as linked lists and trees.

  Functions in C Functions are an important aspect of programming in C. They allow you to break your code into smaller, reusable parts, making it easier to understand, test, and maintain. In this tutorial, we will discuss how to declare and define functions in C.

Declaring Functions Before you can use a function in your program, you need to declare it. A function declaration tells the compiler the name of the function, the type of value it returns (if any), and the types of arguments it expects. Here's the syntax for declaring a function: rust Copy code return_ type function_name (argument_ type argument_name , ...); Let's break down this syntax: return_type is the type of value that the function returns. It can be any valid C data type, including void (if the function does not return a value). function_name is the name of the function. I...
