How to show an address in memory?

Question

C++ / C#

Good afternoon!
Not long ago I learned that through printf(“%p”, &var);You can see exactly where the variable lies.
The question is, how can I do the same without using the printf?
Ps For witty commentators, I’ll explain, the problem is not how and where to output (at least to paper through a printer), but how to get an address in memory that can be printed ...
I don’t need any ready-made functions. And infa from debuggers too. Roughly speaking, I want to do this:

char *moya_func(void *ptr);

int main(void)
{
    void *ptr;
    napechatat_v_printer_adres(moya_func(&ptr));
    return 0;
}

Answer 1

You can use any other console output function (conio, system api). But it will be the same.

Answer 2

With the help of the debugger (and profiler), you can see a lot more interesting things.
