Compiler for arithmetic expression with three address code using flex and bison

Arithmetic Expression Compiler using Flex & Bison

It was tasked to convert arithmetic expression to Three Address Code (TAC) so that

• b+a: digits of number b that are not in number a are added to the end of a.
• b-a: digits of number b that are in number a are removed from a.
• b*a: the digit resulting from the sum of the digits (or the sum of the digits) of the number b is added to the end of a if it does not exist in a.
• b/a: the digit obtained from the sum of the digits (or the sum of the digits) of the number b, if it exists in a, is removed from a.

We created Lexical phase with Flex and Syntax Analysis and TAC with bison. Arithmetic priority also included.

How to Use

gcc  -o Proj2 Lexical.lex.c SyntaxInter.tab.c VarClass.c -lm

Note
