> Also I believe it is defined to compare equal to zero in the standard, but don't quote me on that. That's true for the literal constant 0. For 0 in a variable it is not necessarily true. Basically when a literal 0 is assigned to a pointer or compared to a pointer the compiler takes that 0 to mean whatever bit pattern represents the null pointer on the target system. |
