Conventional C discusses: "If a null pointer regular is transformed to some pointer form, the resulting pointer, identified as a null pointer, is certain to Evaluate unequal to some pointer to any object or function." Technically then This is a valid pointer. Hence, a null pointer is often assigned, passed, returned, and compared. Notice that a null pointer consistent is "syntactic sugar". It's only a means of representing an idea in code. Repeat just after me 1024 situations, or at the very least create a for loop to generate these types of output: It doesn't mean that a subsequent null pointer has all zero bits -- so employing a union pun, or calloc(), or memset(), etcetera isn't a portable tactic for getting null pointers (or for environment floating points to zero possibly though It really is being outlined).
