✨ C2pp 🔮 - C to C++ Code Transformer

C2pp is a powerful tool that magically transforms your C code into modern C++ code. With an intuitive Streamlit interface, you can easily convert legacy C code to take advantage of C++ features and best practices.

✨ Features

C2pp intelligently converts:

• C-style includes to C++ equivalents (stdio.h → iostream)
• #define directives to const declarations
• structs to classes with proper methods
• printf/scanf to cout/cin
• malloc/free to new/delete
• And many other C constructs to their C++ counterparts

🚀 Installation

Prerequisites

• Python 3.7 or higher
• pip (Python package installer)

Setup

1. Clone this repository:

   git clone https://github.com/yourusername/c2pp.git
   cd c2pp

2. Install the required dependencies:

   pip install -r requirements.txt

   Or install them directly:

   pip install streamlit

🔮 Usage

1. Start the Streamlit app:

   streamlit run app.py

2. The app will open in your default web browser.

3. Enter your C code in the left panel or use one of the provided examples.

4. Click the "✨ Cast Translation Spell ✨" button to transform your code.

5. View the translated C++ code in the right panel.

6. Download the translated code using the "📥 Capture Magic Code" button.

🧙‍♂️ How It Works

The translator analyzes your C code and performs the following transformations:

1. Header Conversion: Changes C headers like stdio.h to C++ equivalents like iostream
2. Struct to Class: Converts C structs to C++ classes with methods
3. Memory Management: Replaces malloc/free with new/delete
4. I/O Operations: Converts printf/scanf to cout/cin
5. Constants: Transforms #define constants to C++ const declarations

📋 Example

Input (C Code):

#include <stdio.h>
#include <stdlib.h>

#define MAX_SIZE 100

struct Point {
    int x;
    int y;
};

void printPoint(struct Point *p) {
    printf("Point: (%d, %d)\n", p->x, p->y);
}

int main() {
    struct Point *p = (struct Point *)malloc(sizeof(struct Point));
    p->x = 10;
    p->y = 20;
    printPoint(p);
    free(p);
    return 0;
}

Output (C++ Code):

// C++ style includes
#include <algorithm>
#include <iostream>
#include <cstdlib>

// Using standard namespace
using namespace std;

// Constants (converted from #define)
const int MAX_SIZE = 100;

// Class converted from struct Point
class Point {
public:
    int x;
    int y;

    // Constructor
    Point() {}

    // Methods
    void printPoint();
};

// Method implementations for class Point
void Point::printPoint() {
    cout << "Point: (" << this->x << ", " << this->y << ")" << endl;
}

// Main functions
int main(int argc, char* argv[]) {
    Point *p = new Point;
    p->x = 10;
    p->y = 20;
    p->printPoint();
    delete p;
    return 0;
}
