In later versions of C#, there is the concept of named arguments, such as this:

static int CalculateBMI(int weight, int height)
{
    return (weight * 703) / (height * height);
}
. . .
var a = CalculateBMI(weight:100, height:60);

Does such a concept exist in C++, and if so, how is it used?

Researched thus far: Kernighan & Ritche, "C Programming Language" 2nd ed (okay, I know it's C, but still a good starting point)

There is no native support for it. Boost has an attempt for it. Every hack has its drawbacks – WhiZTiM Feb 17 '17 at 16:21
This question seems fine to me. I don't know why there was a downvote. Hopefully it will be explained. – wally Feb 17 '17 at 16:22
it shows no research. – Daniel A. White Feb 17 '17 at 16:23
@DanielA.White I agree, but so does every other basic language question on SO that has 3000 upvotes. – Millie Smith Feb 17 '17 at 16:23
@DanielA.White I will edit to show the research I've done thus far... – Aaron Thomas Feb 17 '17 at 16:24

A quick google search would show it is not supported by the language. No reason to ask after doing that. (not the down voter) – NathanOliver Feb 17 '17 at 16:24

Ok, now I know. But just want to register but for someone not familiar with C++ this is not as easy to find out as everyone seems to think. Even the title of the duplicate question has several words that throw off the scent of what I'm basically after, ie "Boost", "Idiom". – Aaron Thomas Feb 17 '17 at 16:29
Sure it is. All I did was type "named parameter c++" into the Stack Overflow search. – Cody Gray - on strike Feb 17 '17 at 16:46
There exists a better concept in c++ namely http://en.cppreference.com/w/cpp/language/user_literal making your parameters typesafe. – Surt Feb 17 '17 at 17:04
