Lexical and Syntactic Analyzer in C++

This repository contains a comprehensive Lexical and Syntactic Analyzer implemented in C++ for programming language processing. The code is structured to efficiently tokenize and parse source code, adhering to specified grammar rules.

Features

• Lexical Analysis: The code includes an extensive lexical analyzer (scanner function) that breaks down the input source code into tokens. These tokens are identified based on various categories like identifiers, literals, operators, and reserved words.
• Syntactic Analysis: Utilizing a series of grammar rules and state transitions defined in accompanying CSV files (slr_action.csv and slr_desvio.csv), the analyzer performs syntactic analysis. It checks the structure of the token sequence against the defined grammar.
• Error Handling: Both lexical and syntactic errors are identified and reported, offering insights into the specific location (line and column) of the error within the source code.

Components

1. Main Analyzer Code: The core functionality is encapsulated in the provided C++ file.
2. SLR Transition Tables: Two CSV files representing the SLR (Simple LR Parsing) transitions used in the syntactic analysis phase.

Usage

• Compile the C++ code in a standard C++ environment.
• The SLR transition tables should be in the same directory as the executable for the analyzer to function correctly.
• Input your source code to be analyzed, and the program will output the tokens, syntactic structure, and any errors encountered.
