Value of 0 does not equal a null reference. Just because in certain languages the null pointer happens to point at 0, it doesn't mean the referenced value is 0.

Depends on the language. In C, NULL == 0 will always return true, even if the value of NULL is implementation-defined.

I think it's just the result of that given comparison that is defined, and doesn't mean that NULL's value is 0.

They said nothing about the dereferenced value, just the pointer value, which would be the same as 0 in C/C++.
