Basics of Compiler Design
Introduction
When we have learnt different programming languages like C, C++ or Java we got familiar with the term compiler. As an example, for C and C++ we have found Turbo C compiler, for Java we have seen Java compiler and so on. Most of the students have a wrong idea that compilation is required only to check the errors. But this is not the only job for a compiler, its job is much wider than error checking. Compiler is basically built on the knowledge of Automata. To learn different phases of compiler we need the knowledge of Finite Automata, Regular Expression, Context Free Grammar etc. Compiler needs a vast discussion, but in this section we shall discuss only those parts which are directly related to Automata. ...
