The important thing to notice about file paths is that they are relative to current working directory, not (necessarily) the path at which you find the executable!

Let's say, for instance, your executable resides in /someLocalPath/myProject/bin and you do on command line:

cd /someLocalPath/myProject
bin/myExe some parameters

Then, as current working directory is myProject, you'll find the output file in someLocalPath, not myProject

To get a hint at where to look, you could print the current working directory to console, have a look at std::filesystem::current_path for how to get.
