Why do I have to import Quartz Framework, but not Core Graphics Framework?

Structures are defined entirely in the headers and thus you only need to import the proper header to use them.

Structures are defined entirely in the headers and thus you only need to #import the proper header to use them. To call a function or a method on a class the method needs to be defined in a header and linked at compile time. Importing a framework or library informs the linker which frameworks/libraries to link to.

Note: it is best to only link to the frameworks you require since adding additional frameworks increases amount of work the loader will have to do.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
