Hello everyone!
I'm learning win32 api and have a few questions which I can't find any easy answers to. It would be great if someone could explain them!

So what I've understood so far is that Win32 uses C, wherein I have to write my own code to deisgn the window, i.e. the old fashioned way.

And MFC are C++ classes, like a wrapper around Win32. It makes designing easier by the drag and drop functionality.

But what is SDK?

And is there a difference between MFC functions/objects and MFC CObject API?

My concepts are all over the place right now....so it would be really awesome if someone could help me understand.
Thanks a lot for the help!! I really appreciate it!
