Having surveyed the landscape of Modern C++, it's now clear why it stands as a predominant language in many disciplines like finance, artificial intelligence, and web development. The evolution from C++11 to C++20 has brought a range of powerful features that improved the usability, efficiency, and performance of the language. The auto keyword, range-based for loops, and the simplified initialization of complex containers are only the tip of the iceberg, setting the bar high for clean and efficient code.

Modern C++ is not just about the new features. It’s about a change in style of programming to enhance code readability, reliability, and performance.

For instance, imagine a web development scenario where a server-side component is written in C++. Utilizing the auto keyword could enable efficient handling of the various types of request data, thus simplifying the process. In an AI model written in C++, using range-based for loops to traverse large datasets can make the code significantly faster and easier to maintain.

Embracing Modern C++ equips you with the tools and the mindset to tackle significant and complex tasks in various domains. As you continue in your learning journey, consider the broader implications of these features and how they impact different aspects of your future projects.

#include <iostream>

#include <vector>

using namespace std;

​

int main () {

  // Initializing a Vector

  vector<int> v = {20, 30, 40, 50};

  // Using `auto` & range-based loops for efficient traversing

  for (const auto &i: v) {

    cout << i << ' ';

  } // Prints: 20 30 40 50

  return 0;
