WebPointer in C is just a variable that could store the address of the other variable. In C size of a pointer is not fixed as it depends on Word size of the processor. In general a 32-bit computer machine then size of a pointer would be 4 bytes while for a 64-bit computer machine, it would be 8 bytes.
