Calculator-rs

This project is designed to help you become familiar with the Rust programming language by implementing a calculator with a lexer and parser. The calculator supports basic arithmetic operations and serves as a practical way to understand lexer and parser concepts using object-oriented programming (OOP) logic.

Features

• Arithmetic operations: addition, subtraction, multiplication, division.
• Use of brackets.
• Order of Operations (BEDMAS, PEMDAS).
• Lexer to tokenize the input equation.
• Parser to interpret the tokens and calculate the result.

Getting Started

To run this project on your local machine, follow these steps:

1. Clone the Repository:

   Begin by cloning this repository to your local machine using the following command:

   git clone P34R1/calculator-rs

2. Navigate to Project Directory:

   Change your current directory to the project directory:

   cd calculator-rs

3. Run:

   To run the project, use the following command:

   cargo run

   This will execute the calculator program, allowing you to input an equation and receive calculated results.

Usage

The project consists of the following main components:

• lexer: This module defines the Lexer struct and its associated methods to tokenize the input equation.
• parser: This module defines the Parser struct and its associated methods to interpret the tokens and calculate the result.
• main.rs: The main function in the src/main.rs file demonstrates how to use the Lexer and Parser to calculate equations.

By default it

• Asks for your equation.
• Attempts to Lex and Parse your equation, handling errors if any.
• Prints the answer to your equation.

Feel free to modify the test statments, perform multiple equations, or experiment with the code to further practice Rust programming concepts.

Contribution

While this project is designed as a learning exercise, contributions are welcome. If you have improvements, bug fixes, or additional features to suggest, feel free to fork the repository, make your changes, and submit a pull request.
