Proper way to print - think C++ 23+

[Brad Jones]

I'm curious -

What is the proper way to print in a modern C++ program. Don't think about how you've aways printed with the simply using cout like this:

#include <iostream>

int main() {
    std::string message = "The number is";
    int number = 42;


    std::cout << message << ": " << number << std::endl;
    return 0;
}

Rather think C++ 23. Where things like format have been added:

#include <iostream>#include <format>

int main() {
    std::string message = "The number is";
    int number = 42;

    std::cout << std::format("{}: {}\n", message, number);
    return 0; }

Or would you now do it using std::print?

#include <print> 
int main() {
    int number = 42;
    std::string message = "The number is";

    std::print("{}: {}\n", message, number);
    return 0; }

Or is std::print not yet fully accepted, and thus the best way is to use format?

Again, I don't care as much about what people are doing, but rather about what people SHOULD Be doing if they are following current, modern standards.

Thoughts?
