# Simple Lex/Yacc Calculator

This is a simple calculator implemented using Lex and Yacc. It supports basic arithmetic operations, square root, exponentiation, and modulo operation.

## Features

- **Basic Arithmetic Operations**: The calculator can perform addition, subtraction, multiplication, and division.

- **Square Root**: The calculator can compute the square root of a number using the `sqrt()` function.

- **Exponentiation**: The calculator can perform exponentiation using the `^` operator.

- **Modulo Operation**: The calculator can perform modulo operation using the `%` operator.

- **Error Handling**: The calculator can handle syntax errors and division by zero errors.

- **Commands**: The calculator supports commands for displaying help instructions (`h`) and quitting the application (`q`).

## Usage

To use the calculator, simply enter an expression or a command. Here are some example expressions for each feature:

- **Basic Arithmetic Operations**: 

  - Addition: `2 + 3`

  - Subtraction: `5 - 2`

  - Multiplication: `4 * 5`

  - Division: `20 / 4`

- **Square Root**: `sqrt(9)`

- **Exponentiation**: `2^3`

- **Modulo Operation**: `10 % 3`

- **Commands**: 

  - Display help instructions: `h`

  - Quit the application: `q`

Please note that spaces are not allowed in the expressions.
