Well "Find any errors in the following BankAccount constructor: Public int BankAccount() { balance = 0; } a) Name b) Formal parameters c) Return type - correct answer d) No errors " - it's public not Public.

I had stopped reading in disgust long before that....

I was in too much pain after reading the first 18 questions and couldn't carry on.

The ThreadPriority enumeration does not contain: a) Lowest b) Highest c) BelowNormal d) None of the above - correct answer :((

I think that effort must put you close to the top of the high-scores table.

After reading your post i started from bottom but stupidness extends till the bottom hole.

Synchronization is: a) the delaying of a thread until there is sufficient memory and work to keep it up b) making every thread start and end at the same time c) make each thread do the same thing d) have each thread start at the same time but not necessarily finish together b,c and d are utterly BS, but I also don't want to click on a :sigh:

[Andre xxxxxxx]

a) True - correct answer b) (your answer) False I've only used C++/CLI and if I declare a method as abstract and omit the abstract keyword behind the class I get a warning, but I can also declare a class as abstract without even any abstract methods. Is this not true for C#?

[Rage]

32. Synchronization is: a) the delaying of a thread until there is sufficient memory and work to keep it up - correct answer :confused: :omg:

[Lost User]

Wowowow :omg: Just some of the mistakes: (disclaimer: I just woke up so I may have seen mistakes where there are none) 11) String mystring; Creates a(n) e) depending on the context it may define a private field or reserve a local slot. 12) An Event is d) a collection of delegates which you may add or remove that you (not the user) can invoke all at once 14) should be a. It's possible, not always - but still possible 16) What is the proper header for a class that intends to use an interface. f) none, there are no headers in C#. 17) "create an interface objects" and what is that supposed to mean? It doesn't even look like correct English to me. 20) Polymorphism occurs when the methods of the child class. e) nothing. It occurs when you have a child class. 21) To output the value of multidimensional array, Console.WriteLines(___) e) myArray[1,3] because the thing at A is a jagged array, not a multidimensional one. 22) All methods in an abstract base class must be declared abstract. It's b. Unless that makes it "just an abstract class" instead of an "abstract base class". But it's silly to call it "base" anyway - it's not required that you derive from it somewhere. 27) A method_____an exception when that method detects that a problem has occured. e) does whatever it bloody wants. Maybe it pretends nothing happened, or it returns -1, or an error code, or calls Environment.Exit() or maybe it blows up the universe. 30) A____block enclose the code that could throw an exception. f) scope. You don't have to catch it, but it will at least have a scope block around it. 32) answer A is slightly.. odd.. but the "and work" makes it technically true. 37) In order to lock/unlock an object use the. e) please use the lock keyword (but B would work..)

[Lost User]

You don't even get a warning.

I've choosen a) because ToLower() returns a copy of the string X| a) (your answer) String = string.ToLower(string); b) ToLower(string); c) string.ToLower(); - correct answer d) string.ToLower(string);

[molesworth]

The correct answer is "none of the above". Normally, I'd use newstring = oldstring.ToLower(); The optional parameter is a CultureInfo string, if you want formatting for a particular culture setting. However, using "String" or "string" as variable names is going to throw up compile errors. PS - that quiz is an abomination which should be removed before anybody gets the wrong impression of C# :)

[Pete OHanlon]

All methods in an abstract base class do not have to be declared abstract. You can't instantiate an abstract base class, but you can provide default functionality. What you must do, is provide an implementation of abstract functionality in any derived classes. You, also, can't declare a method as abstract if it's not in an abstract class. Honestly, this test is rubbish.

I know, but I thought the questioner wanted to see if we know that ToLower() returns a copy, but obviously that was not his intention X|

Ok, so Harold was wrong with his answer. In C++/CLI

ref class A
{
virtual foo() = 0;
};

gives a warning because of the missing abstract behind the class. But in C++ you can also provide a default implementation of a method AND declare it as abstract (pure virtual).

class A
{
virtual foo() = 0
{
doSomething();
}
}

If C# does not force me to declare every method as abstract, the test is wrong here again.
