NULL == 0?

[KarlisRepsons]

Why are people writing "NULL" - it is longer!?

[seymore15074]

Not only that, but Bjarne Stroustrup specifically recommends the use of 0.

Thanks, is what I've done this far...

I think the use of NULL comes from the how C handles the null pointer constant; it is often defined along the lines of:

#if C++
#def NULL 0
#else C
#def NULL ((void*)0)
#end

NULL!=0, NULL is speciall .I think I have read that in some books.

As an aside, in the upcoming C++0x (although it will most likely end up being C++10), nullptr will be introduced. Unlike NULL, it will be a keyword and have type. Its type will be nullptr_t, which can be implicitly casted to any pointer type. Wikipedia fails to mention its value.

I don't know how I feel about this. It's not a bad idea, but 0 has kinda grown on me.

Just took a look at the wiki site and what not about C++0x - it doesn't look to bad. But I guess time will tell.
