c++ Default paramaters: is it possible to override a default parameter without overriding earlier default parameters

Question

I have a function:

int function(int a, int b = 1, int c = 2){
    return a+b+c;
}

I want to set the value of the "c" variable to 3, but don't want to set the value of "b"

In a language like python I can do this:

function(23,c=3)

However in c++ I cant find a way to do something like that. All examples I could find involved setting the value of "b" before the value of "c", like this:

function(23,1,3);

How can I set the value of a default parameter directly?

Answer 1

This is not possible in C++ (at least not directly). You have the provide all parameters up to the last one you want to provide, and in the order given by the declaration.
