Q: Why was MagicMock designed a independent thing rather than just folding the ability into the default mock item?

Nonetheless, should you go digging inside the STL resource code in your compiler, you'll likely see code that both isn't really normal, or which you're not imagined to write oneself. The STL may be implemented entirely in conventional C++, but that does not necessarily mean compiler writers aren't allowed to further improve it often, working with compiler-precise extensions.

For long term google people: An additional solution is placing the %MAGIC% enviroment variable in the systems environment to point towards the magic file, for me it absolutely was:

In addition they continually use names that you're not allowed to use. Such as, template parameters are generally named one thing like _Type, which, since it starts off using an underscore followed by a capital letter, is reserved with the implementation

The point that a constant is used or not named isn't The difficulty. In the case of my dreadful case in point, the value influences conduct, but Let's say we have to alter the value of "i" while looping?

Like gbjbaanb the right way reported, the STL is usually executed in simple C++, devoid of counting on any type of compiler "magic".

Folks sometimes just take magic quantity elimination even further, by going these constants into independent documents to work as configuration. This is sometimes helpful, but could also create a lot more complexity than It is really truly worth.

The phrase magic quantity is usually made use of to describe some numeric continuous in code. The number seems with none even more description and thus its meaning is esoteric. Using magic figures could be avoided by making use of named constants. Share Strengthen this response Adhere to

Does the basic worth Have a very semantic or intent associations with other primary values in precise contexts?

That's why it is best to possess these types of ambiguous and arbitrary figures in exactly one location - "const int NumOrdersToDisplay = fifty", due to the fact that makes the code additional readable ("if a magician < NumOrdersToDisplay", In addition, it means You simply need to vary it in 1 perfectly outlined put.

As Jalf mentions, working with these names operates the risk that your code should have name clashes With all the libraries A part of your compiler (or another a single when somebody else made an effort to compile your code), so clearly employing them is a foul idea.

For instance, let's say there is a Site that shows the last 50 Orders in a "Your Orders" Overview Web site. fifty would be the Magic Amount here, because it's not established by way of normal or convention, it is a range that you just created up for factors outlined in the spec.
