This book was particularly designed for new students taking their first curriculum lesson, but it is also welcome for everyone interested in studying C to review. It is intended to complement lectures in the classroom with a focus on C programming. The subjects are arranged on the basis of the order of lecture. In addition to modifications in the language and presentation of programming, there were other sections. At the end of the chapter are listed some common questions and scheduling errors. Here you will only tackle a subset of the ANSI C language. In particular, the student is assumed to be working with ANSI C (which supports ANSI C) or the Borland Turbo C / C++ compiler in Windows under the Linux environment and programming. There are also standards for coding to be followed and a few pointers for programming using the Linux environment. May you learn a great deal from this manual study and may the knowledge you've gained be used for everyone's common good.
