The absolute first program in the book—the hello world program—is not able to be completed since the book uses a custom header file for nearly all of its content. The std_lib_facilities.h header file isn’t listed on the authors website, nor can I find a valid solution to this problem. I can absolutely create my own header file with the same content and just copy and paste it into my project directory, but that’s too much work for each program that I plan on making.
Do I really need this custom header file, or could I just include whatever my compiler tells me I need? Also, The header file uses namespace std I believe so there’s no std:: or anything like that. Will I be getting into a bad habit and/or cheating myself out of a portion of learning by not including the needed header files on my own for each individual program?
