The extensions to C standardized by ANSI (the American National Standards Institute) offer important new and improved elements to the language which will be welcomed by newcomers and experienced programmers alike. Moreover, most modern C compilers such as those from Microsoft, Borland and Zortech conform to the new standard. This book is based on the author's own experience of teaching and programming in C. It presents the complete language (including ANSI library functions), uses carefully selected examples and includes numerous exercises, making it an ideal textbook as well as a useful reference source. For more advanced programmers, the book covers subjects such as: functions with variable-length argument lists; efficient searching and sorting; linear lists; binary trees; and solving systems of linear equations.
