Learn some new languages by creating calculators.
We'll start with a basic calculator (add, subtract, multiply, divide). Over time, we'll do scientific, financial, and then graphing calculators.
- Basic Operations: The calculator must perform the four fundamental arithmetic operations: addition, subtraction, multiplication, and division.
- Result Display: After computing the result, the calculator should display it clearly and then prompt the user for another input. This allows for continuous use until the user decides to exit.
- Exit Capability: Users should be able to exit the program using a specific command (e.g., 'exit' or 'quit').
- Error Handling: Implement basic error handling for unexpected or malformed inputs to prevent the program from crashing.
- Instructions for Use: When the program starts, it should display instructions on how to use the calculator, including the format of the input and how to exit.
- Unit Testing: Provide unit testing for each tool/language.
- Handling Division by Zero: The program should handle attempts to divide by zero appropriately, providing an error message instead of crashing or producing a nonsensical result.
- Repeat Calculations: The calculator should allow users to perform multiple calculations sequentially without needing to restart the program.
- Enhanced Console UI: Provide a cleaner UI with support for arrow keys, etc.
- User Input Validation: The program should validate user inputs to ensure they are numerical values where expected and handle non-numerical inputs gracefully, either by rejecting them or by displaying an error message.
- Floating Point Arithmetic: The calculator should support floating-point arithmetic to allow for more precise calculations with decimals.
- Variables: Support for variables, e.g., A=1, B=1+A ... displays: 2
- Web Interface: Should provide a basic HTTP server that accepts input and responds with the calculator result.
- Unit Testing: Unit testing should be updated.
- UI Testing: UI testing to ensure proper handling of input, etc.
