Earth, then the answer is: We tend to use null only for pointers. If you're not, don't use null. If either the above statements are true, I would think that doing something like "int var null would generally be a bad idea.

This is how we can write such portable code as: void strcpy(char *to, char const *from) while to *from, therefore it's _not_ just habitual conversion. Null is never '0 null.

On some machines a null is not 0, so assigning null to a non pointer variable generates trash.Use the right types for all your assignments.Then 1) can be reasonably assured that the desired result was acheived.

Your compiler should explain arnovitz to you why null is never defined writing in that way. I thought that the definition of null was at least in some instances void. I remember that this is a bad practice.

There's no guarantee that a int reinterpret_casted to a pointer yields a null pointer value.If I saw the code: int MyVar null; I would immediatly presume that MyVar is being cast to a pointer somewhere and is not acutally used as an integer.
