How to load my file directly? What is that path for the file I want to use fopen to read in C++?

Hi,

I am using images as my data storage and I had done the system that read and put the image into the format I want.
However, I can’t find where to put the images, and I try to write some file to find the position but the new file is not under the project.

I imported the file I am using, but the tutorials I found are loading images as texture, not char*. I followed the path they are using but it didn’t work. (I don’t know what I was using at the moment basically.)

Now I put the images as assets instead, but the image is uassest now and I don’t think I can use the same way to read it since the size of the file had been changed.

Is there any way to read a file just like you only work in C++?
