My Pascal Lab class and now java?

If you got the OOP concepts down, you should be able to pick up Obj-C without problem IMO. If not you can get a hang of if through Python, or just look for some online material describing object oriented analysis, or a book.

 

You have to learn OOP with some OO language. If it's java or objective-C... you'll get to the same place. If the java class isn't a pre-req for the iPhone class you want to take, I wouldn't say it's strictly necessary. If the description of the iPhone class says the course assumes you are familiar with OOP principles, you'll need to be. But if pascal is the pre-req I would have to think they'd cover objective-C including OO concepts along with cocoa touch specifics.

Some Pascal dialects are object-oriented.

 

Java is a nice learning language for OOP. Objective C is sort of a mix between OOP and a procedural language (C), which can make it confusing. In other words, I agree with your TA. There a lot of good learning material on Java. Also, it's a widely used language in the industry so it's worth learning on its own merits. Pascal, on the other hand, is pretty much dead except as a learning language.

 

what's the difference between objective-C and C++? I thought C is procedural, and C++ is the object-oriented extension of C??

 

The fundamental difference between Objective-C and C++ is that Objective-C requires platform infrastructure support (like libraries + frameworks) while C++ is a tool that compiles standard procedural object code written in an object-oriented source structure. C++ can be used within Objective-C (is available to Cocoa programmers) and is used as the support structure behind the IOKit part of Mac OS used to write device drivers.

 

so a truer comparison should be between say objective-c and visual c++ for windows needing the platform infra. support?

 

Older than this (http://edn.embarcadero.com/article/20803) version of Turbo Pascal?

 

ahhh...that makes sense. Thanks!
