Code Organization and Project Structure

Proper project structure improves maintainability.

Recommended Structure

MyProject/
├── include/
│   └── myproject/
│       ├── utils.h
│       ├── config.h
│       └── types.h
├── src/
│   ├── utils.cpp
│   ├── main.cpp
│   └── CMakeLists.txt
├── tests/
│   ├── test_utils.cpp
│   └── CMakeLists.txt
├── CMakeLists.txt
└── README.md

Header Organization

utils.h

#ifndef MYPROJECT_UTILS_H
#define MYPROJECT_UTILS_H

// 1. Includes
#include <string>
#include <vector>

// 2. Forward declarations
class Config;

// 3. Constants
constexpr int MAX_SIZE = 100;

// 4. Function declarations
int calculate(int x);

// 5. Classes
class Utils {
public:
    static void process();
};

#endif

Source Organization

utils.cpp

// 1. Module headers
#include "utils.h"

// 2. System headers
#include <iostream>

// 3. Implementation
int calculate(int x) {
    return x * 2;
}

Best Practices

1. One class per header file
2. Use include guards
3. Group related functionality
4. Keep headers self-contained
5. Use forward declarations when possible
