About the Project

This project is a simple implementation of a Regular Expression (regex) matcher in C++. It provides a command-line interface for matching input strings against a given regex pattern. The regex engine supports a subset of the standard regex features, including:

• Literal characters
• The wildcard character .
• Character classes []
• Start and end of line anchors ^ and $
• Grouping and alternation |
• Quantifiers ?, +
• Escape sequences \d, \w

Getting Started

To get a local copy up and running, follow these simple steps:

1. Clone the repo
2. Compile the C++ file using a C++ compiler (e.g., g++)
3. Run the compiled program from the command line, passing the -E flag and your regex pattern as arguments.

Prerequisites

This project is written in C++ and requires a C++ compiler. The code is compatible with C++11 and later versions.
