File I / O from the current position of Windows C ++

I have not yet found a definitive answer about this. I am trying to access files in subfolders from my .EXE. When I asked before, people tell me to use an absolute location, that is, "c: / game / info /" if I wanted to access anything in / info /

But for me or someone it is completely unreasonable to assume that someone is going to use their program from the same directory. What if the user has only a D-disk? That kind of thing.

So my question is: how can I access the file in a subdirectory from my executable without relying on the whole path?

Create or use an installer that asks the user where to install the executable file and writes this registry path in a known place for later reference.

if you use:

#include <fstream>

ifstream stream("file");

he will work. "file" is the file in the directory with your exe. Of course, if you want to go up or down the folder hierarchy, use ".. \ file" or "folder \ file"
