Perl build, unit testing, code coverage: A complete working example
...
It took me a while and it also took me taking small snippets from a number of different sources and melting them together, but I think I have a small working example that sufficiently demonstrates to a Perl newbie the Perl build process including unit testing and code cove...

What is the difference between Debug and Release in Visual Studio?
... result some lines of your code might get left without any instructions at all, or some might get all mixed up. Step-by-step debugging would be impossible. Also, local variables are often optimized in mysterious ways, so Watches and QuickWatches often don't work because the variable is "optimized aw...
What's the point of 'const' in the Haskell Prelude?
...
It's useful for passing to higher-order functions when you don't need all their flexibility. For example, the monadic sequence operator >> can be defined in terms of the monadic bind operator as
x >> y = x >>= const y
It's somewhat neater than using a lambda
x >> y =...

Setting variable to NULL after free
... int *nPtr=NULL;. Now, I would agree that this would be redundant, with a malloc following right in the next line. However, if there is code between the declaration and the first initialization, somebody might start using the variable even though it has no value yet. If you null-initialize, you get ...
