I have been reading through the Becoming an XCoder pdf and the user
Guids for XCode and I can't figure something out. In the guide it
gives you a sample program that calculates the area of a circle and a
rectangle, it says to press the build and go button and the results
will be displayed in the run log. I cannot find the runlog box. I
found a box called build results that displays the results, errors
and
the returned state but not a box that displays the output of the
program. I have no errors in the code according to XCode. Do I have
to
enable something to display the results or am I hitting the wrong
button?
What you are looking for is the "console". It sounds like you may
have the
three-page all-in-one view in Xcode 3. In Xcode 3, the console
window only
seems to show in the debugger window, so you can go to the debugger
(Run->Debugger menu). IIRC, in Xcode preferences, in the "debugging"
options, I set "On Start" to "Show Console" to show the debugger/
console on
run. I may be wrong about that, but it sounds right.
I am in a Visual Basic course right now and my teacher is having us
declare variables with Hungarian notation. I have been coding C and
Bash shell scripts in Linux for a few years and have never done it,
nor have I ever seen it in a book.
Sounds like your teacher is rather old-school. What you describe is a
convention commonly known as Hungarian "System" notation. Originally
developed for use in a non-typed language, it found usefulness in
strongly-typed structured languages. There are good reasons or using
it, but
I believe most modern compilers can detect the types of issues that
the
convention is trying to prevent (such as trying to stuff an int into a
char), and in any case other conventions have superseded it.
In particular you will find that Objective-C/Cocoa tends to use a
convention
similar to the Hungarian "Apps" notation, were the purpose of the
symbol is
incorporated into the name, although not always (or usually) as a
prefix.

Thanks for the tips, you were right. You are right about the teacher
he tells us the same sad story every week about being a cobol and ada
programmer in the 70's then getting into web design and then Visual
Basic and Visual C++. It is useless to try and speak up in the class,
teacher knows best I guess.
