txtC to Three-Address Code Translator
The language txtC is a programming language created for educational purposes base on ansi C. Its purpose is to add support for text manipulation to C language. In order for that to happen, a string type was added as a native data type and the functions below were created to manipulate strings and text files.
The software developed for this project is a translator from txtC to a three-address code. It is divided in four parts: lexical, syntax and semantic analyzers followed by an intermediate code generator.
Technologies: C, Three-address Code, LEX, Yacc, Bison and LaTeX.
