What kind of car?

They used to be. Go back far enough in time and you could climb up under the hood into the engine bay to work on it. All that went by the wayside to get smaller packaging, lighter weight, and better fuel efficiency.

Now you need special tools or special code readers to solve/diagnose all vehicle problems. The large scale farmers are dealing with this now with the large combines and harvesters needing a tech with special equipment to read all the codes where the older tractors from the 70s and 80s can be repaired.

Well, nothing to do but start at the first one and work our way down…

Try the c++23 standard. There’s been a lot of cross pollination. Contrived example follows:

#include <format>
#include <numbers>
#include <print>
#include <string>

int main(int argc, char *argv[]) {
    double pi = std::numbers::pi;
    std::string fstr = std::format("{}, {:>.2}, {:>.5}, {:>.10}", pi, pi, pi, pi);
    std::string h = "Hello";
    std::string w  = "World";
    std::println("{}, {}!", h, w);
    std::print("This won't have a {},", "newline");
    std::println(" but this will add it."); // Add a newline.

    // Can't put a non-constant string as the first argument to
    // print or println so they can be checked at compile time.
    std::println("{}", fstr);
    return EXIT_SUCCESS;
}
