Magic numbers become particularly confusing when the same number is used for different purposes in one section of code. It is easier to alter the value of the number, as it is not duplicated. Changing the value of a magic number is error-prone, because the same value is often used several times in different places within a program. [6]
For example, when testing a program that takes a user's personal details and verifies their credit card number, a developer may decide to add a magic string shortcut whereby entering the unlikely input of "***" as a credit card number would cause the program to automatically proceed as if the card were valid, without spending time verifying it.
Such signatures are also known as magic numbers or magic bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible. However, some file signatures can be recognizable when interpreted as text.
These limits are not really magic numbers, they are fundamental. The article Integer (computer science), to which redirects, has them, but only in decimal (and in a sense they are "magic" in decimal as seemingly arbitrary, whereas in hex they are plainly not). I am tempted to add the hex into the Integer article and delete this section: there ...

As such, the compiler must also generate "hidden" code in the constructors of each class to initialize a new object's virtual table pointer to the address of its class's virtual method table. Many compilers place the virtual table pointer as the last member of the object; other compilers place it as the first; portable source code works either ...
The magic number is the total number of outcomes that have to go right for a team to secure a playoff spot. Right now, that means any combination of Brewers wins or losses by the second-place team ...
It also identifies, gathers, and creates redirects to all article sections about JavaScript (for example, the links Comment (JavaScript) and Comments in JavaScript redirect to Comment (computer programming)#JavaScript). In addition, we identify gaps in JavaScript coverage, and plan coverage for missing topics by maintaining a list of needed ...
