This book is on the C programming language and explores all the important elements of C, such as strings, arrays (including one-dimensional and two-dimensional arrays), functions, pointers, file handling, threads, inter-process communication, database handling, advanced data structures, graphs, and graphics. As this book takes the cookbook approach, the reader will find independent solutions to different problems that they usually come across while making applications. By the end of the book, the reader will have sufficient knowledge to use high- as well as low-level features of the C language and will be able to apply this knowledge to making real-time applications.
