📚 Modern C++ Tutorial: C++11/14/17/20 On the Fly | https://changkun.de/modern-cpp/

Quick Overview

Awesome Modern C++ is a curated list of resources for modern C++ development. It provides links to various tools, libraries, frameworks, and learning materials that focus on C++11 and later standards. This repository serves as a comprehensive guide for developers looking to stay up-to-date with the latest C++ practices and technologies.

Pros

  • Extensive collection of high-quality resources for modern C++ development
  • Regularly updated with new content and community contributions
  • Well-organized into categories for easy navigation
  • Includes both beginner-friendly and advanced resources

Cons

  • May be overwhelming for newcomers due to the large amount of information
  • Some linked resources might become outdated over time
  • Lacks detailed descriptions or reviews of individual resources
  • Primarily focuses on external links rather than providing in-depth content within the repository

Code Examples

As this is not a code library but a curated list of resources, there are no specific code examples to provide.

Getting Started

As this is not a code library, there are no specific getting started instructions. However, users can begin exploring the resources by visiting the GitHub repository at https://github.com/rigtorp/awesome-modern-cpp and browsing through the categorized lists of links.

Guidelines Support Library

Pros of GSL

  • Provides actual implementation of guidelines and utilities
  • Backed by Microsoft, potentially more stable and well-maintained
  • Offers concrete tools for safer C++ programming

Cons of GSL

  • Focused solely on Guidelines Support Library, less comprehensive
  • May require additional setup and integration into projects
  • Limited to specific C++ safety and usage patterns

Code Comparison

GSL example:

#include <gsl/gsl>

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

Awesome Modern C++ doesn't provide code, but might reference:

#include <vector>
#include <algorithm>

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

Summary

GSL offers concrete implementations for C++ best practices, while Awesome Modern C++ serves as a curated list of resources. GSL is more focused but provides actual code, whereas Awesome Modern C++ covers a broader range of modern C++ topics without implementation. The choice between them depends on whether you need specific tools (GSL) or a comprehensive guide to modern C++ resources (Awesome Modern C++).

CppCoreGuidelines

42,437

The C++ Core Guidelines are a set of tried-and-true guidelines, rules, and best practices about coding in C++

Pros of CppCoreGuidelines

  • Comprehensive set of guidelines for writing modern C++ code
  • Officially supported by the C++ Standards Committee
  • Regularly updated with new C++ standards and best practices

Cons of CppCoreGuidelines

  • Can be overwhelming for beginners due to its extensive content
  • Focuses primarily on guidelines rather than providing a curated list of resources
  • May require more time to navigate and find specific information

Code Comparison

CppCoreGuidelines example:

void f(int* p, int n)   // BAD: pointer argument
{
    // ...
}

void f(span<int> a)     // GOOD: span argument
{
    // ...
}

Awesome Modern C++ example:

// No direct code examples provided, as it's a curated list of resources
// However, it links to various code examples and libraries

Awesome Modern C++ is a curated list of resources for modern C++ development, including libraries, tools, and articles. It provides quick access to a wide range of C++ resources but doesn't offer direct guidelines or code examples.

CppCoreGuidelines, on the other hand, is a comprehensive set of guidelines for writing C++ code. It offers detailed explanations and code examples but may require more time to navigate and find specific information compared to the concise list format of Awesome Modern C++.

awesome-cpp

58,586

A curated list of awesome C++ (or C) frameworks, libraries, resources, and shiny things. Inspired by awesome-... stuff.

Pros of awesome-cpp

  • More comprehensive, covering a wider range of C++ topics and libraries
  • Regularly updated with new resources and contributions
  • Includes sections for job boards, podcasts, and talks

Cons of awesome-cpp

  • Less focused on modern C++ features and best practices
  • May include outdated or less relevant resources due to its broader scope
  • Navigation can be more challenging due to the large number of categories

Code comparison

While both repositories primarily focus on curating lists of resources rather than providing code examples, awesome-modern-cpp occasionally includes short code snippets to illustrate modern C++ features. For example:

awesome-modern-cpp:

std::vector<int> v = {1, 2, 3, 4, 5};
auto sum = std::accumulate(v.begin(), v.end(), 0);

awesome-cpp doesn't typically include code snippets, focusing instead on categorizing and listing resources.

Summary

awesome-cpp offers a more extensive collection of C++ resources, covering a broader range of topics and including additional categories like job boards and podcasts. However, awesome-modern-cpp provides a more focused approach to modern C++ features and best practices, occasionally including code snippets to illustrate concepts. The choice between the two repositories depends on whether you're looking for a comprehensive list of C++ resources or a more targeted collection of modern C++ information.

C-Plus-Plus

30,039

Collection of various algorithms in mathematics, machine learning, computer science and physics implemented in C++ for educational purposes.

Pros of C-Plus-Plus

  • Provides actual implementations of algorithms and data structures
  • Offers a hands-on learning experience for C++ programming
  • Includes a wide variety of algorithms across different domains

Cons of C-Plus-Plus

  • May not always follow modern C++ best practices
  • Lacks curated resources for learning modern C++ concepts
  • Focuses more on algorithmic implementations rather than language features

Code Comparison

awesome-modern-cpp typically doesn't include code snippets, as it's a curated list of resources. C-Plus-Plus, on the other hand, provides full implementations. Here's an example of a simple algorithm from C-Plus-Plus:

// Binary Search implementation
int binary_search(int arr[], int l, int r, int x) {
    if (r >= l) {
        int mid = l + (r - l) / 2;
        if (arr[mid] == x)
            return mid;
        if (arr[mid] > x)
            return binary_search(arr, l, mid - 1, x);
        return binary_search(arr, mid + 1, r, x);
    }
    return -1;
}

This code demonstrates the practical nature of C-Plus-Plus, providing ready-to-use implementations for learners and developers.

📚 Modern C++ Tutorial: C++11/14/17/20 On the Fly | https://changkun.de/modern-cpp/

Pros of modern-cpp-tutorial

  • Provides a structured, tutorial-style approach to learning modern C++
  • Offers in-depth explanations and examples for each concept
  • Available in multiple languages (English, Chinese)

Cons of modern-cpp-tutorial

  • Less comprehensive coverage of C++ resources compared to awesome-modern-cpp
  • May not be as frequently updated as awesome-modern-cpp
  • Focuses primarily on C++11/14/17, with less emphasis on newer standards

Code comparison

modern-cpp-tutorial:

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

awesome-modern-cpp (example from a linked resource):

std::vector<int> v = {1, 2, 3, 4, 5};
auto sum = std::accumulate(v.begin(), v.end(), 0);

Summary

modern-cpp-tutorial is a structured learning resource for modern C++, offering detailed explanations and examples. It's ideal for those seeking a guided approach to learning C++11 and beyond. However, it may not cover as wide a range of topics or be as frequently updated as awesome-modern-cpp.

awesome-modern-cpp serves as a curated list of resources, providing links to various C++ libraries, tools, and learning materials. It offers a broader overview of the modern C++ ecosystem but doesn't provide in-depth tutorials itself.
