So that it can perform arithmetic and other operations. Consider these two examples:

int* p; /* let the address of the memory location p pointing to be 1000*/
p++;
printf("%u",p); /* prints 1004 since it is an integer pointer*/


char *p; /* let the address of the memory location p pointing to be 1000*/
p++;
printf("%u",p); /* prints 1001 since it is an char pointer*/

I hope this helps you !
