Find out how to determine the performance of the application and all about the varied algorithms for sorting and exploring--both of those frequent difficulties when programming.
As an optimization, you might want to reuse a buffer as a scratch pad, but even then prefer to limit the variable’s scope as much as you possibly can and be cautious never to lead to bugs from knowledge left within a recycled buffer as it is a popular source of protection bugs.

The compiler is more probable to find the default semantics right and You can not put into practice these features a lot better than the compiler.
By stating the intent in resource, implementers and tools can offer greater diagnostics, like acquiring some lessons of problems by way of static Evaluation, and perform optimizations, for instance eradicating branches and null tests.
