C Language Parser

This is my first work in language design field. It was my “Language Implementation and Design” project in IUST University. It takes a standard C program. Then it recognizes variables, constants, statements, loops and other standard programming structures. In each step it tries to simplify the current step by replacing equals in the language table like :

VarDecl ----> Type ID;

VarDecl ----> Type ID[num];

Expr ----> ID = ID

Expr ----> ID = num

Stmt ----> If Expr StmtList else StmtList
