# Windows Forms Calculator Application

## Overview

This repository contains a simple calculator application built using Windows Forms in C#. The calculator supports basic arithmetic operations and has features for evaluating complex expressions with parentheses and handling square root operations.

## Features

- **Basic Arithmetic**: Supports addition, subtraction, multiplication, and division.

- **Complex Expressions**: Allows for multiple operations and parentheses for operator precedence.

- **Square Root Calculation**: Can compute the square root of the current input or the result displayed.

- **Dynamic Display**: Adjusts the font size dynamically to fit longer expressions in the display.

- **Keyboard Support**: Allows numeric and operation input via the keyboard.

## Components

### Main Form (`mainApp`)

- **Controls**: The form includes buttons for digits (0-9), arithmetic operations (`+`, `-`, `*`, `/`), special functions (square root, parentheses, clear, delete, and toggle sign), and equal for evaluating the expression.

- **Label**: `lbl_answer` displays the current input or result, dynamically adjusting its font size based on the length of the text.

### Key Functionalities

1. **Numeric Input**:

    - Handled through both button clicks and keyboard input.

    - Appended to the current `input` and reflected in the `expression` for display.

2. **Operation Handling**:

    - Adds operation signs (`+`, `-`, `*`, `/`) to the `expression`.

    - Supports continuation of operations after the equal button is pressed.

4. **Expression Evaluation**:

    - Uses the `DataTable.Compute` method to evaluate the full expression, considering operator precedence and parentheses.

    - Updates the `expression` to display the result after evaluation.

5. **Square Root Calculation**:

    - Computes the square root of the current input or the displayed result if no new input is provided.

    - Updates the `expression` to reflect the square root operation result.

6. **Dynamic Font Adjustment**:

    - Adjusts the font size of `lbl_answer` based on the length of the text to ensure readability.

7. **Keyboard Input Handling**:

    - Supports numeric input and operations through keyboard shortcuts.

    - Allows users to control the calculator without using the mouse.
