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

There is no null keyword in C (at least in ANSI C99). You could use a) or c).

In c) you'll not initialize pointer with null, you'll initialize it with address of local variable.
