What is a bit copy?

Anonymous

∙ 15y ago

Updated: 12/22/2022

A bit copy of an object is an exact, bit-by-bit, copy of that object. The default copy constructor generated by the compiler makes a bit copy.

This is potentially a problem if the object contains pointers to other objects...

A bit copy of a pointer copies the pointer, but not its data. This means that you have two pointers pointing at the same object in memory. If you delete one of them, the other becomes invalid, and this can (usually does) cause corruption.

If an object contains a pointer, the object's copy constructor should provide for proper allocation and copying of any pointed to objects within that object.

Downloading a cracked version of a video game is a form of - what?

Generally what is occurring when a game is "cracked" is that the copy protection has been defeated - so the cracked copy is an illegal copy - violating the copyright of the entity owning the copyright. In simple terms- it is usually theft. If someone downloads a cracked copy of a game they already own and does not share that game with anyone else, the issue is a bit murky.

What does it mean when a confederate coin has the word copy stamped on it?

It means it's not real! A copy is exactly that, a replica of the real thing. However, it's not considered a counterfeit because the maker followed the law and marked the coin with COPY to indicate that there is no intent to deceive anyone about its origin. It's a bit like a print of a famous painting.
