Boolean Algebra Post-fix Notation Calculator

Project Overview

This project implements a post-fix notation calculator for Boolean algebra using Flex and Bison. The calculator can evaluate Boolean expressions using the values TRUE and FALSE and the operators AND, OR, NOT, and XOR.

Features and Functionalities

  • Accepts both capital and lower-case letters for TRUE and FALSE.
  • Supports the operators & (AND), | (OR), ! (NOT), and XOR (exclusive OR).
  • Input can be provided through keyboard and calculations are performed when Enter is pressed.
  • Program exits on the end-of-file character (CTRL+d).

Usage

To compile and run the calculator:

  1. Compile using Flex and Bison with the provided boolcalc.l and boolcalc.y files.
  2. Run the generated executable.
  3. Input the Boolean expression in post-fix notation and press Enter to evaluate.

Examples

INPUT: TRUE FALSE &
OUTPUT: FALSE

INPUT: true false xor
OUTPUT: TRUE

INPUT: TRUE!
OUTPUT: FALSE

INPUT: tRuE FaLsE & ! fAlSe |
OUTPUT: TRUE
