simple Pointer initialization

Question

It has been a while that I used pointers and I just wanna quickly check how I can initialize an integer pointer?

a) int *tmpPtr = 0;

b) int *tmpPtr = null;
         


        

Answer 1

I was just refreshing my pointer knowledge and stumbled across this.

int *tmpPtr = 0;

i find it easier to think of it like this:

int *tmpPtr ;

tmpPtr = 0 ;

I 'believe' the above 2 lines are equivalent to that one line. so basically the address to be de-referenced is set to 0 or NULL.
