: The series provides a strong crossover with Theory of Computation (TOC), making it easier for students to see the direct application of automata in real-world compiler construction. Neso Academy like Syntax Analysis or some practice problems from the GATE syllabus? Fuel | Neso Academy

Understanding how the compiler keeps track of variable names, types, and scopes.

The lexical analysis phase involves breaking the source code into a series of tokens. These tokens are the basic building blocks of the programming language, such as keywords, identifiers, literals, and symbols. The lexical analyzer, also known as the lexer or tokenizer, reads the source code character by character and groups them into tokens.
