What is datatype of pointer?

Posted By :Abhisek Panda     Posted Date :July 27, 2010    Points :10   Category :OOPS 
Pointer can be of any datatype and is not restricted to the size of that particular datatype. Pointer is a variable of 4byte as all address in a 32 bit computer are of 4 byte length. So what about 64 bit computers? Well in 64 bit computers the pointer size will vary, but if we rum a 32 bit pointer in 64 bit system then we will find half of the pointer's field is empty like 0x000000.
