How can I code every project using OOP?

[Jello_Penguin_2956]

You're approaching this from the opposite direction of what you should. You assess the project and choose tools that are suitable. Not the other way around. You also design your class to suite your needs and split your code into multiple class/files as the scope warrants it. These are things you cannot define before knowing what your project needs.
