#### 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 transpose of a matrix using pointers

The best part of this recipe is that we will not only display the transpose of the matrix using pointers, but we will also create the matrix itself using pointers.

The transpose of a matrix is a new matrix that has rows equal to the number of columns of the original matrix and columns equal to the number of rows. The following diagram shows you a matrix of order 2 x 3 and its transpose, of order 3 x 2:

Figure 5.29

Basically, we can say that, upon converting the rows into columns and columns into rows of a matrix, you get its transpose.

# How to do it…

1. Define a matrix of 10 rows and 10 columns as follows (you can have a bigger matrix if you wish):
`int a[10...`
