A further form of magic number, nevertheless, is Utilized in file formats. It is really just a price bundled as typically the first thing in the file which helps detect the file format, the Variation of the file format and/or maybe the endian-ness of The actual file.
By way of example, they could insert non-regular code that guarantees superior mistake messages, or perhaps will work around some flaw inside their compiler, or maybe enables Particular optimizations by making use of extra features of that precise compiler.
So by your definition, my reply is most definitely accurate. For the rest of us, it is a bit more iffy, mainly because the rest of us use "STL" to confer with a subset of your regular library, and There are a variety of ordinary library functions in C++eleven which demand compiler "magic". But is there overlap concerning those functions as well as "STL" component? I don't Assume so.
In uncomplicated and genuine words and phrases, a magic range is A 3-digit selection, whose sum of your squares of the first two digits is equal to the third one.
Let's put our lone "two" within a context of: padding := Lisa 2, wherever the context is actually a "GUI Container". Within this context the this means of two (as pixels or other graphical unit) features us a quick guess of its semantics (meaning and reason).
Get paid badges by enhancing or inquiring thoughts in Staging Ground. See new badges What are magic figures and why carry out some contemplate them terrible?
The result is ALL fundamental values are changed with symbolic constants. As I agree with your summary I uncover this below great.
I'm not notably keen on the technological particulars, but largely in how I induced it And exactly how I am able to prevent it Later on. Here is some notes on the problem:
Some people did - STLPort is undoubtedly an implementation that did not have the backing of any compiler producer.

It goes into a certain amount of depth about the entire methods the magic range reference is produced. Here is a quotation about magic amount as a foul programming apply The expression magic number also refers to the lousy programming apply of working with numbers right in resource code with out rationalization.
