c++ set functions specific default argument

[Gyiove]

Hello everyone!

I'm not quite if I've seen it around, I did not find it on internet but
I believe that there was a way to set an specific argument while calling a function and leaving other's untouched.

Something like this:

void example( a = 5, b = 10, c = 15 ){ cout << a << "," << b << "," << c << endl; }
int main(){
    example( .b=20 ) // prints:5,20,15
    example( .c=100 ) // prints:5,10,100
    return 0
}

or perhaps I'm just confusing everything with another programming language
and that method does not exist at c++ at all.
Thanks!

Personally, I can't believe that you ask a pretty ridiculous question here even though you have up to 168 posts on the forum.

Do you need to learn C++ Default Parameters from scratch?

Perhaps I'm blind or very stupid but I fail to see what I requested.
Take a closer look of my request.

C++ does not have named parameters. There is a workaround. See:

PS. Ignore the incompetent troll.
