# Arithmetic Expression Evaluator
This is a C++ project that evaluates infix arithmetic expressions by converting them to postfix notation (Reverse Polish Notation) for calculation.
## Features
- Converts infix expressions to postfix.
- Evaluates the resulting postfix expression.
- Supports operators: `+`, `-`, `*`, `/`, `^`.
- Handles multi-digit and decimal numbers.
- Includes parenthesis handling.
- Error validation for invalid expressions (e.g., unbalanced parentheses, division by zero).
## How to Compile and Run
You can compile the project using g++. Make sure you have a C++ compiler compatible with C++11 or higher.
```bash
g++ -I include example.cpp src/evaluator.cpp src/posfix-evaluator.cpp -o example
```
if linux user could use:
```
compile.sh
```
Once compiled, you can run the example program:
```bash
./example
```
## Example Usage
- Example 1:
- Example 2:
## TODO
1. Add trigonometrics expressions handlers
2. Add params support
3. Add evaluation by prefix notation
