A textbook for undergraduate courses (B.E., B.Tech, B.Sc. CS, MCA/IT) covering foundational theory of computation: formal languages, grammars, automata, computability, and complexity. Emphasizes examples, solved problems and chapter-end exercises to support teaching and learning.

There are dozens of textbooks on automata theory (Hopcroft & Ullman, Peter Linz, Michael Sipser), but why does C.K. Nagpal’s edition remain a favorite for Indian undergraduate programs?

A: Partially. It covers 95% of Automata Theory for GATE. However, for GATE, you will need additional material for the "Compiler Design" and "Data Structures" sections, which are separate subjects.
