Pros of GSL

• Provides a set of standardized C++ core guidelines support libraries
• Backed by Microsoft, ensuring high-quality and well-maintained code
• Focuses on improving safety, reliability, and performance in C++ programming

Cons of GSL

• Steeper learning curve for beginners compared to Modern C++ Tutorial
• Less comprehensive coverage of modern C++ features and concepts
• Requires more advanced C++ knowledge to fully utilize and implement

Code Comparison

GSL:

#include <gsl/gsl>

void example(gsl::span<int> arr) {
    for (int& i : arr) {
        i *= 2;
    }
}

Modern C++ Tutorial:

#include <vector>
#include <algorithm>

void example(std::vector<int>& arr) {
    std::for_each(arr.begin(), arr.end(), [](int& i) {
        i *= 2;
    });
}

The GSL example uses the gsl::span type for safer array access, while the Modern C++ Tutorial example demonstrates the use of standard library containers and algorithms.

Pros of CppCoreGuidelines

• Comprehensive set of guidelines for writing modern C++ code
• Backed by the C++ Standards Committee, ensuring high-quality and up-to-date information
• Covers a wide range of topics, from basic syntax to advanced concepts

Cons of CppCoreGuidelines

• Can be overwhelming for beginners due to its extensive coverage
• Lacks practical examples and hands-on tutorials
• Focuses more on best practices rather than teaching language features

Code Comparison

CppCoreGuidelines example (Rule C.47):

class Vector {
public:
    Vector(int s);
    ~Vector() { delete[] elem; }
    // ...
private:
    double* elem;
    int sz;
};

modern-cpp-tutorial example (Chapter 2.6):

class Foo {
public:
    int value() const;
    void set_value(int v);
private:
    int value_;
};

CppCoreGuidelines provides more detailed explanations of best practices, while modern-cpp-tutorial offers simpler examples to introduce language features. The CppCoreGuidelines example demonstrates proper resource management, whereas the modern-cpp-tutorial example focuses on basic class structure and encapsulation.

Pros of modern-cpp-features

• Concise and focused on specific C++ features
• Regularly updated with the latest C++ standards
• Well-organized with clear categorization of features

Cons of modern-cpp-features

• Less comprehensive tutorial-style content
• Fewer explanations and examples for each feature
• Limited coverage of broader C++ concepts and best practices

Code Comparison

modern-cpp-features:

// C++17 structured bindings
auto [x, y, z] = std::tuple{1, 2, 3};

modern-cpp-tutorial:

// C++17 structured bindings with explanation
auto [x, y, z] = std::tuple{1, 2, 3};
// This allows us to unpack the tuple into individual variables
std::cout << x << y << z << std::endl; // Outputs: 123

The modern-cpp-features repository provides a more concise overview of C++ features, while modern-cpp-tutorial offers more detailed explanations and examples. modern-cpp-features is better suited for quick reference, whereas modern-cpp-tutorial is more appropriate for in-depth learning and understanding of modern C++ concepts.

Pros of awesome-modern-cpp

• Comprehensive collection of resources covering various aspects of modern C++
• Regularly updated with new links and resources
• Well-organized into categories for easy navigation

Cons of awesome-modern-cpp

• Lacks in-depth explanations or tutorials
• May be overwhelming for beginners due to the sheer volume of resources

Code comparison

modern-cpp-tutorial:

auto add = [](int x, int y) { return x + y; };
std::cout << add(1, 2) << std::endl;

awesome-modern-cpp: No direct code examples provided, as it's primarily a curated list of resources.

Summary

modern-cpp-tutorial offers a structured learning path with detailed explanations and code examples, making it ideal for beginners and those looking for a comprehensive tutorial. awesome-modern-cpp, on the other hand, serves as an extensive reference guide, providing a wide range of resources for various aspects of modern C++. While it may not offer direct tutorials, it's an excellent resource for finding specific information and staying up-to-date with the latest developments in the C++ ecosystem.

Both repositories have their merits, and developers may find value in using them complementarily. modern-cpp-tutorial can provide the foundational knowledge, while awesome-modern-cpp can be used for further exploration and deepening one's understanding of specific topics in modern C++.

Pros of cppbestpractices

• Comprehensive coverage of C++ best practices, including coding style, design patterns, and performance optimization
• Regularly updated with community contributions, reflecting current industry standards
• Includes sections on tooling, testing, and project management

Cons of cppbestpractices

• Less structured learning path compared to modern-cpp-tutorial
• Lacks in-depth explanations of modern C++ features
• No hands-on examples or exercises for practical application

Code Comparison

modern-cpp-tutorial:

auto add = [](int a, int b) { return a + b; };
std::cout << add(1, 2) << std::endl;

cppbestpractices:

// No specific code examples provided, as it focuses on general guidelines rather than code snippets

The modern-cpp-tutorial repository provides more concrete code examples to illustrate modern C++ features, while cppbestpractices focuses on high-level guidelines and best practices without specific code implementations.

Both repositories serve different purposes: modern-cpp-tutorial is a structured tutorial for learning modern C++ features, while cppbestpractices is a comprehensive reference for writing high-quality C++ code. Developers may find value in using both resources complementarily to improve their C++ skills and knowledge.
