Pointers in C

We are working on the detailed description of this book, we will update this section soon.

This document is intended to introduce pointers to beginning programmers in the C programming language. Topics covered includes: What is a pointer, Pointer types and Arrays, Pointers and Strings, Pointers and Structures, Arrays of Strings, Multi-Dimensional Arrays, Pointers to Arrays, Pointers and Dynamic Allocation of Memory and Pointers to Functions.

This document explains how pointers and memory work and how to use them from the basic concepts through all the major programming techniques. For each topic there is a combination of discussion, sample C code, and drawings.

This note covers the following topics: Pointers in C, Pointers as Arguments, Passing Pointers to a Function, Code Using Pointers, Null Pointer, Syntax for Pointer Operators, C Code for IntDivide, Arrays , Array as a Local Variable, Passing Arrays as Arguments, I/O with Strings, Arrays, Pointers and Pointer Arithmetics.

This note covers the following topics: Pointers, Memory, Two Operators , Declaration, Passing Pointers to Functions , Multiple Return Values, Arrays, Strings and Dynamically Allocating Arrays.

In computer science, a pointer is a programming language object, whose value refers to another value stored elsewhere in the computer memory using its memory address. Topics covered includes: Memory-mapped hardware, Typed pointers and casting, Making pointers safer, Null pointer, Autorelative pointer, Based pointer, Multiple indirection, Function pointer, Dangling pointer, Back pointer, Pointer declaration syntax, Wild branch, Simulation using an array index.

This note covers the following topics: Pointers, Sizes of basic data types, Address Operations, Pointer Arithmetic, Arrays and Pointers, Schematic Diagram of num elts, Passing Pointers to Functions
