Can anyone teach me how to create a library for c++

Question

create a library for c programming

Answer 1

Did you really need to programm a library for C++?
Use Librarys that are already existing like Sftml, Allegro or SDL for 2D graphics and graphic output.

Answer 2

yes...since library is a collection of classes and functions,we can program our own library..furthermore if we use any librarys that are already exist,we are using the third party work which mean the program is not purely by you..i saw my electrical engineering senior program his own library for c++ which simplify his robotic project..but im too afraid to ask how does he do that because we are not even close to each other and im a junior to that super-senior..
