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.

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:

./example

Example Usage

• Example 1:

• Example 2:

TODO

1. Add trigonometrics expressions handlers
2. Add params support
3. Add evaluation by prefix notation
