Proper practice for subclassing UIView?
...rsion here:
If your class mostly consists of subviews, the right place to allocate them is in the init methods. For views, there are two different init methods that could get called, depending on if your view is being instantiated from code or from a nib/storyboard. What I do is write my own setup ...
What does the thread_local mean in C++11?
... (exists for the program duration) and dynamic (exists on the heap between allocation and deallocation).
Something that is thread-local is brought into existence at thread creation and disposed of when the thread stops.
Some examples follow.
Think of a random number generator where the seed must ...
Is it abusive to use IDisposable and “using” as a means for getting “scoped behavior” for exception
..."using", I don't know to ask the question; I assume that the "using" block allocates a resource, uses it for a bit, and politely disposes of it when it is done, not that the closing brace of the "using" block mutates my program state in an exceptional cirumstance when arbitrarily many program state ...

Is recursion a feature in and of itself?
...airly expensive compared to iteration (in general) because it requires the allocation of a new stack frame. Not to mention you can get a stack overflow exception if the input is not valid too many times.
I believe the professor deducted points since recursion is considered a subject of its own and ...

What is an IndexOutOfRangeException / ArgumentOutOfRangeException and how do I fix it?
...ith a limitation: they can't grow, if you need more elements you need to reallocate that array (this may take a relatively long time if old items must be copied to a new block). You resize them with Array.Resize<T>(), this example adds a new entry to an existing array:

Cleanly exiting a function
Often in a function, you may allocate resources and need to exit in multiple places. Programmers can simplify their code by putting the resource cleanup code at the end of the function, and all "exit points" of the function would goto the cleanup label....
