str2 is a pointer. It points to a constant string: "are you ?"
Constant strings are NOT allowed to be changed, as they are hard coded 
into the exe. So the problem lies here, and not in any sort of 
dereferencing. However, in the first case, the thing is different, as 
you have an array (str1), not a pointer, and you initialise this array 
with a string.

Try this, and it will work:

char str3[] = "are you ?";
char str2 = str3;

I hope this helped.
