C-Like Language Compiler

This project is a C-like language compiler implemented using Flex (lexical analyzer) and Bison (parser generator) as part of a university project at the Computer Engineering and Informatics Department (CEID).

Features

• Lexer: The Flex file (flex.l) contains the rules for tokenizing the input source code.
• Parser: The Bison file (bison.y) defines the grammar and rules for parsing the tokens generated by the lexer.
• Input Files: The input files (input.txt, input2.txt, input3.txt) contain correct grammar of the C-like language.
• Wrong Input File : The wronginput.txt file containt incorrect grammar of the C-like language.

Language Constructs

The C-like language supported by the compiler includes the following constructs:

• Variables: Declare and use variables of integer and character types.
• Control Flow: Support for if-else statements, while and for loops, and switch-case statements.
• Functions: Define and call functions.
• Print Statement: Print statements using the print keyword.
• Comments: Support for single-line and multi-line comments.
• Data Types: Integer (int) and character (char) data types.
• Arrays: Declaration and usage of arrays.

How to Run

To compile and run the C-like language compiler, follow these steps:

1. Install Flex and Bison: Ensure you have Flex and Bison installed on your system.
2. Compilation: Open a terminal, navigate to the project directory, and run the following commands:

flex lexer.l
bison -d parser.y
gcc lex.yy.c parser.tab.c -o compiler
