Looking ahead to C++20, we have some exciting features coming up, particularly useful for our reader's deep interest in AI and finance. One such feature includes the introduction of the std::format library, which provides robust text formatting capabilities similar to those provided by printf, but in a simpler and more type-safe way.

This is a game-changer, especially when working with large datasets in AI or finance, as it allows for more readable and maintainable code.

A simple example is as follows:

1#include <iostream>
2#include <format>
3using namespace std;
4int main() {
5  // C++20 introduces the format library for text formatting
6  string s = format("Hello, {}!", "World");
7  cout << s;
8  return 0;
9}

Here, std::format function generates a new string, replacing the {} with the given parameter. This makes the code more readable and easier to maintain, thereby making life easier for coders in AI and finance industries.

In the next screen, we will look at more such features and their implications in data-driven sectors like AI and finance.

#include <iostream>

#include <format>

using namespace std;

int main() {

  // C++20 introduces the format library for text formatting

  string s = format("Hello, {}!", "World");

  cout << s;

  return 0;

}
