It is actually well worth noting that in some cases you do want non-configurable "really hard-coded" numbers with your code. There are a number of popular kinds which include 0x5F3759DF that is Utilized in the optimized inverse square root algorithm.
If by STL you signify just the template percentage of the C++ Common Library, then it's properly achievable to put into practice it with none "magic".
However, SO must be capable to stand by itself even though the remainder of the Online disappears! By all means website link to a different supply, but I choose to put some meat in the answer at the same time.
Right here "2" is a "magic" number, that's factored out to some symbolic continuous default_padding within the context of your GUI UX of "my method" in an effort to ensure it is use as default_padding speedily understood within the bigger context with the enclosing code.
We've two situations for our magic standard values. Only the second is of Principal importance for programmers and code:
Whether Every presented implementation basically uses any "magic" is another question (you'll find parts of STL in which "magic" would support, although not absolutely necessary).

Within the use point of view, there is absolutely no "magic", no Distinctive dependencies you've to deal with. It can be used on any Krol key C++ compilers, on all platforms supported by All those compilers.
Magic numbers are any variety in your code that may not promptly obvious to another person with very little information.
Therefore it is actually unachievable to help make an implementation of the article and String lessons in pure(*) Java. Now This is certainly what I indicate with "magic": to generate an implementation of those classes, you will require some Exclusive aid with the compiler.
In the event you have an interest in Discovering this, you are able to obtain a "absolutely free" Edition with the software that only operates with sqlite databases termed UniPaaS Jet.
I did some googling and could not come across Significantly information about it. I could not uncover any code examples, and wikipedia didn't have any info on it both.
. The standard library is allowed to make use of them, but you and I are usually not. So when you ended up heading to write down your personal STL implementation, you would need to make some minor alterations, but which is not as a result of any magic, simply a way to prevent identify clashes between the common library and person code.
