The term "magic" has its place in programming history, and generally referred to something that is either understood by those who are experts, or understood by no one, as to How It Works.
Magic numbers in C and other programming languages today have a number of meanings:
- a constant value used to identify a protocol or file formats (file signatures);
- unique identifiers unlikely to be mistaken to mean other things;
- values whose usages are unexplained.
Some interesting examples of magic numbers include:
- Java bytecode files start with 0xCAFEBABE, but compressed with "Pack200" the code becomes 0xCAFED00D (this is magical);
- image files start with unique identifiers like "GIF89a", "GIF87a", or begin and end with unique values;
- Mark Zbikowski designed the EXE file format, which starts with MZ (0x5A 0x4D), ensuring at least part of his name was burned into the annals of history;
- On older systems, newly allocated or freed memory was marked with the 32-bit hexadecimal value 0xDEADBEEF, and initializing memory came to be known in some circles as "deadbeefing the memory" or "the memory is deadbeef".
