Formal languages are sets of strings of symbols that are used to communicate with machines. They provide a way to specify the structure and syntax of a language, and are used to define the input and output of automata. Formal languages can be used to model natural languages, programming languages, and other types of symbolic systems.
Pandey’s book is primarily designed for undergraduate students of computer science (B.Tech, B.Sc, BCA) and information technology. Unlike the dense, proof-heavy tomes intended for graduate students, Pandey adopts a .
