I'm trying to build an Operating System from scratch, and the problem with that is, that you can't use libraries like iostream, string, etc.. So that makes me have to make my own libraries and frameworks.
I want to read the contents of a .txt file, and then I want to print the text of the .txt file.
I haven't tried anything so far, because I only found questions using std::string and string.open, which I can't use.
So I want to know how open contents of a .txt file without using any libraries
Sorry for an bad English
