Learn C first before learning Objective-C [closed]
...ecesscary to learn C first. Especially if you already know a language like C# of Java. C# and Java owe much to objective C. Though C# owes alot more to Helsbergs experience and mistakes with Delphi.

Declare a const array
...e-time. The array initializer you've shown is not a constant expression in C#, so it produces a compiler error.

It doesn't - the C# compiler does :)
So this code:

string y = "there";
string z = "chaps";

Here's the same function written in C#:

Why is UnhandledExceptionEventArgs.ExceptionObject an object and not an Exception?
...in .Net that do not derive from System.Exception. This is not possible in C# or VB.Net but it is possible in other CLR based languages. Hence the API must support this possibility and uses the type object.
So while it shouldn't ever be null, it may not in fact be a System.Exception.
