Calculator (C11 & GTK4)

School practical work for the subject of Programming Languages, in the Internet of Things Engineering course at the Jiangsu University.

A lightweight & simple calculator application that can perform basic arithmetic operations, based on C11 language with GTK4.

Any questions or suggestions are welcome to contact me via email [email protected] or using issues (recommend) .

Features

• Basic arithmetic operations: addition, subtraction, multiplication, division.
• Basic operations: clear, delete, and equal.
• Advanced operations: square root, cubed root, and factorial, etc.
• Based on double numbers.
• Support for keyboard & mouse input.
• Simple & Elegant UI.

Development

This project depends on GTK4, so make sure your system has installed the related runtime libraries.

This project is developed using the CLion IDE and built with CMake, so you need to install minGW-w64 and CMake to compile and develop normally.

Design

• Structure: Functions are implemented by classification, and each class is responsible for a separate function.
• Interface: Use GTK4's CSS style sheet for interface design, which is simple and elegant.
• Logic: Use state machine design to implement operators for easy expansion.
• Link: Use GTK4's signal and slot mechanism to separate the interface from the logic.
