Practical C Programming

By: B. M. Harwani

Overview of this book

Used in everything from microcontrollers to operating systems, C is a popular programming language among developers because of its flexibility and versatility. This book helps you get hands-on with various tasks, covering the fundamental as well as complex C programming concepts that are essential for making real-life applications. You’ll start with recipes for arrays, strings, user-defined functions, and pre-processing directives. Once you’re familiar with the basic features, you’ll gradually move on to learning pointers, file handling, concurrency, networking, and inter-process communication (IPC). The book then illustrates how to carry out searching and arrange data using different sorting techniques, before demonstrating the implementation of data structures such as stacks and queues. Later, you’ll learn interesting programming features such as using graphics for drawing and animation, and the application of general-purpose utilities. Finally, the book will take you through advanced concepts such as low-level programming, embedded software, IoT, and security in coding, as well as techniques for improving code performance. By the end of this book, you'll have a clear understanding of C programming, and have the skills you need to develop robust apps.

Working with Arrays

Arrays are an important construct of any programming language. To keep data of a similar type together, we need arrays. Arrays are heavily used in applications where elements have to be accessed at random. Arrays are also a prime choice when you need to sort elements, look for desired data in a collection, and find common or unique data between two sets. Arrays are assigned contiguous memory locations and are a very popular structure for sorting and searching data collections because any element of an array can be accessed by simply specifying its subscript or index location. This chapter will cover recipes that include operations commonly applied to arrays.

In this chapter, we will learn how to make the following recipes using arrays:

  • Inserting an element into a one-dimensional array
  • Multiplying two matrices
  • Finding the common elements in two arrays
  • Finding the difference between two sets or arrays
  • Finding the unique elements in an array
  • Finding whether a matrix is sparse
  • Merging two sorted arrays into one

Let's begin with the first recipe!
