As pointed out in some of the article's comments, a much better solution would be if all languages allowed putting the name in front of function parameters (and while at it, also not enforce a specific parameter order and skip default-value parameters).

A workaround in C99 (and more limited in C++20) is to use a single struct which bundles all the function parameters, and then use designated initialization, this also makes function paramaters optional, and at least in C99 they can appear in any order:

    my_func((my_struct_t){
        .a_bool_flag = true,
        .another_bool_flag = false,
        .a_string = "Hello World"
    });

This is mainly useful for functions which take many parameters. One downside in C99 (but not C++) is that there's no way to define default values for struct items (other than zero/false).
