Boolean Calculator

The Boolean Calculator evaluates logical expressions by parsing a string that includes variables and operators. It supports NOT, AND, OR, and optional XOR, with parentheses for grouping. Users supply variable values or request a full truth table to inspect all outcomes. Conceptually, the tool tokenizes input, converts to postfix form using operator precedence, and then computes a boolean result. This approach mirrors how digital logic analyzers operate, enabling rapid validation of logic rules without programming. The primary beneficiaries are students learning logic, QA engineers validating business rules, and developers designing feature flags or conditional logic. Unique value lies in instant, reproducible results and the ability to generate complete truth tables for all variable combinations. Core features include automatic variable extraction, fallback handling for missing values, and friendly error reporting for invalid tokens or syntax. Typical use cases include verifying De Morgan transformations, checking complex conditionals in software, and teaching logic simplification concepts. The tool emphasizes correctness, speed, and clarity in logical evaluation, making it suitable for academic, testing, and development contexts.
