Synopsis This book on ANSI C is for readers with a good knowledge of at least one procedural programming language such as Pascal, FORTRAN or Ada. Advanced aspects of C, for example, type declarations, data abstraction, exceptions and the C preprocessor are emphasized. Several examples drawn from a wide spectrum of application areas such as interactive programming, systems programming, database applications, text processing and concurrent programming are included in the book. These are taken from real programs that have been tested. The book also discusses two derivatives of C: C++ and Concurrent C.
