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.

Finding the largest value in an array using pointers

In this recipe, all the elements of the array will be scanned using pointers.

How to do it…

  1. Define a macro by the name max with a size of 100 as follows:
#define max 100
  1. Define a p integer array of a max size, as demonstrated in the following code:
int p[max]
  1. Specify the number of elements in the array as follows:
printf("How many elements are there? ");
scanf("%d", &n);
  1. Enter the elements for the array as follows:
  1. Define two mx and ptr pointers to point at the first element of the array as follows:
  1. The mx...
