How can you learn names of methods or classes of a framework or an API?

I’ve been programming C++ for a year now. I’ve gone through the language features and I’ve written good programs with it, so I decided to move on to OpenGL. At first it seemed confusing. As I kept going through tutorials it appeared to be easier, but I can’t remember the names of classes, methods, arguments, etc.

Why isn’t functional language syntax more close to human language?

I’m interested in functional programming and decided to get head to head with Haskell. My head hurts… but I’ll eventually get it…
I have one curiosity though, why is the syntax so cryptic (in lack of another word)?

Why store a function inside a python dictionary?

I’m a python beginner, and I just learned a technique involving dictionaries and functions. The syntax is easy and it seems like a trivial thing, but my python senses are tingling. Something tells me this is a deep and very pythonic concept and I’m not quite grasping its importance. Can someone put a name to this technique and explain how/why it’s useful?

Checking “instanceof” rather than value using a switch statement

Is there some syntax (other than a series of if statements) that allows for the use of a switch statement in Java to check if an object is an instanceof a class? I.e., something like this:

Why do programming languages, especially C, use curly braces and not square ones?

The definition of “C-Style language” can practically be simplified down to “uses curly braces ({}).” Why do we use that particular character (and why not something more reasonable, like [], which doesn’t require the shift key at least on US keyboards)?
