It may well appear to be somewhat banal, but there's at the very least 1 actual magic selection in each programming language. 0

As "gbjbaanb" rightly stated, there is no magic linked to the implementation of STL. It truly is composed in pure C++. You could carry out it oneself but has long been designed readily available being a library to create your daily life simpler.

What is actually bad about this is that you are reusing an area (that of signed integers for history IDs) for Particular talents. It's possible you'll in no way want to make a report with ID 0, or using a unfavorable ID, but regardless of whether not, each individual person who seems both for the code or within the database may stumble on this and be puzzled to start with.

Therefore it is actually unattainable to create an implementation of the Object and String lessons in pure(*) Java. Now This can be what I suggest with "magic": to produce an implementation of those courses, you will want some Particular guidance with the compiler.

A Magic Number is a hard-coded price which will alter in a afterwards stage, but that may be thus not easy to update.

I did some googling and could not discover much information regarding it. I could not discover any code illustrations, and wikipedia did not have any information on it possibly.

. The common library is allowed to rely on them, however you And that i are not. So in case you were heading to jot down your own personal STL implementation, you would need to make some minor alterations, but that's not as a result of any magic, simply a way to prevent title clashes between the normal library and person code.
