The rationale for why that error is an effective point is presented down below. But very first, here is the most typical Answer: just

In ideal contexts in supply code, such as for assigning to some pointer variable, a null pointer frequent may be created as 0, with or with out specific casting to your pointer sort, or as the NULL macro defined by numerous normal headers. In conditional contexts, null pointer values Consider to Bogus, though all other pointer values Assess to legitimate.
