.... e.g. a block of code for reading rows from a dataReader.
I still don't know exactly why they did this.

It is more verbose in C# 2.0. However, in C# 3 onwards, you can use the "=>" syntax to make some nicely terse expressions.
It is less familiar. People ...
How are POST and GET variables handled in Python?
...
I know this is an old question. Yet it's surprising that no good answer was given.

How to create a fixed-size array of objects
...
The best you are going to be able to do for now is create an array with an initial count repeating nil:
var sprites = [SKSpriteNode?](count: 64, repeatedValue: nil)

@CutbertoOcampo I understand what happened now. The original question was asking for solutions in ANSI C, obviously he wanted answers for C89 only. In 2016 the question was edited and "ANSI C" was removed, which now makes it hard to understand why this answer and comm...
400 vs 422 response to POST of data

How can I push a local Git branch to a remote with a different name easily?

What are bitwise shift (bit-shift) operators and how do they work?
..., you would use the following math:
memoryOffset = (row * 320) + column
Now, back in that day and age, speed was critical, so we would use bitshifts to do this operation.
However, 320 is not a power of two, so to get around this we have to find out what is a power of two that added together make...
C++ Returning reference to local variable
...dies, making the reference returned from the function worthless because it now refers to an object that doesn't exist.
int main()

int& p = func1();
