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.

Storing information in MySQL database

In this recipe, we will learn how to insert a new row into the users table. Recall that at the beginning of this chapter, we created a database called ecommerce, and in that database, we created a table called users with the following columns:

email_address varchar(30)
password varchar(30)
address_of_delivery text

We will be inserting rows into this users table now.

How to do it…

  1. Initialize a MYSQL object:
conn = mysql_init(NULL);
  1. Establish a connection to the MySQL server running at the localhost. Also, connect to the database that you want to work on:
mysql_real_connect(conn, server, user, password, database, 0, NULL, 0)
  1. Enter the information of the new row that you want...
