But it adds flexibility 🙄
Imagine that you want to change which arguments these functions receive. You would have to change every single function definition…
it does add flexibility at the cost of code that doesn't respect the language's scope and linker boundaries

just find and replace on the text editor can let you replace the arguments you are talking about

mmmh, sounds somewhat unclean to me :-/

But I understood the problem. I'll think about it.

It's just inside a header and I don't plan having more than one non-header file

another solution that just came to my mind. if you have similar parameters for a bunch of functions, why not make them into a struct and pass structs (or references or pointers to them) around

Sounds interesting, I'll look into it after a short break 😉

Can you give me a very quick example of what you mean?
Nils
I think I know what you mean but I am unsure

instead of
function1(vector<int> &a, string b, int c);
function2(vector<int> &a, string b, int c);
function3(vector<int> &a, string b, int c);
struct args {
args(vector<int> &a_init, string b_init, int c_init) : a(a_init), b(std::move(b_init)), c(c_init) {}
vector<int> &a;
string b;
int c;
}
and use args objects for each of the three functions
Nils
ahhhhh
Nils
Yeah, that's a brilliant idea

there are more stuff like
https://en.cppreference.com/w/cpp/language/variable_template
https://en.cppreference.com/w/cpp/language/constexpr
https://en.cppreference.com/w/cpp/language/consteval
https://en.cppreference.com/w/cpp/language/type_alias
that can help reduce usage of preprocessor macros. heck C++20's modules replaces even #include (though i don't know if they added export to existing STL libraries)

What is a vu64?
Nils
I can't find anything about it
Nils
Also…
I have a piece of code that runs on CPU "ARM9" of the device, but I'd like to run some code on CPU "ARM7", how would I do that?
Nils
Btw in this case I afaik am at ring 0 (there is no OS behind it)

He did ask "how," too.

Why is that?
just my preference
large function body - stateless -> function, stateful -> named functor
small function body (less than 10 lines) - stateless -> inline function
small function body (less than 5 lines) - stateless -> inline function or lambda, stateful -> lambda

Why the address is always the same?
Anonymous
this android compiler?
Asdew
I don't use C++, but I believe that's because the variable it is always at the same address, with only the value changed. It only creates the variable once.

it's initialised once when init-statement is executed

I'm trying to understand what the iterator is actually doing because if it's pointing to a list then an incrementation seems obvious to me that goes to the next position of the list and change address. Seems like it's not what I think

for (int i = 0; i != 5; ++i) {
std::cout << &i << ' ' << i << '\n';
}
back to being passive aggressive: why do you think the address of i should change?
