PS: Static Examination resources like FindBugs and PMD detects using magic numbers in your code and implies the refactoring.

Such as, they might insert non-typical code that ensures greater mistake messages, or perhaps performs all-around some flaw inside their compiler, Or perhaps enables Specific optimizations by making use of additional characteristics of that unique compiler.

So by your definition, my response is most surely accurate. For the rest of us, it is a little more iffy, because the rest of us use "STL" to check with a subset from the conventional library, and There are a variety of standard library attributes in C++eleven which require compiler "magic". But is there overlap among Those people attributes along with the "STL" part? I don't Consider so.

The expression "magic amount" gets abused a bit, nevertheless, referring to almost just about anything that identifies a file structure - like fairly long ASCII strings during the header.

The fact that a continuing is applied or not named isn't really The problem. In the situation of my awful illustration, the worth influences behaviour, but what if we have to alter the value of "i" even though looping?

I Programmed with Magic for 6 yrs and located it to become a incredibly rapid Software, simple to be familiar with If you're a competent databases programmmer for the reason that all operations are actually about knowledge manipulation.

It truly is surely a niche place create in and for that reason Employment are few and far between. As it truly is interpreted you will find truly no bugs for making. It's going to do the job with several databases/connections at the same time but there is a major memory and processing hit. Negatives :

Like gbjbaanb correctly said, the STL can be implemented in basic C++, with no counting copyright on any sort of compiler "magic".

Within the rare scenarios in which I find the necessity to use these kinds of Magic Numbers, I established them like a const in my code, and document why These are employed, how they work, and wherever they came from.

A theory that's relevant to magic numbers is that each truth your code promotions with must be declared precisely the moment. If you use magic quantities within your code (including the password duration instance that @marcio gave, you can certainly find yourself duplicating that actuality, and when your understand of that simple fact modifications you've a upkeep challenge.

The notion of "default" is not really disclosed. Only After i create: padding = default_padding like a context and afterwards in other places: default_padding = two do I absolutely understand a greater and fuller this means (semantic and goal) of 2 in our procedure.

3 I think about it like employing plain JS vs Jquery. Positive, you can use Jquery to accomplish all of your JS, but in some instances, you merely want to utilize the quite minimal Software required to get The work accomplished. I locate People instances tend to be both the incredibly simple or the very advanced.

Coincidentally, in order to get an idea of what it can be And exactly how it really works, I've observed that comparing it to MS Accessibility is helpful. It works in Substantially precisely the same way from the user's or developer's viewpoint.

in other words, has something been done on the compiler to allow for your 'Particular circumstance' the STL necessary to work?
