Why I Built a Scientific Calculator in Pure C for Terminal Environments
The article discusses the creation of a scientific calculator designed for terminal environments using pure C. The author emphasizes the need for a tool that operates natively in terminal settings without requiring graphical interfaces or external dependencies. Key features include support for advanced mathematical functions, equation solving, and ASCII graph plotting, all while maintaining simplicity in design.
- ▪The calculator is built to function in terminal environments without the need for a GUI or external dependencies.
- ▪It supports advanced mathematical functions, including trigonometric and logarithmic calculations, as well as equation solving.
- ▪The project is intentionally kept as a single file for simplicity, allowing easy understanding and modification.
