int i1,i2; in t*p1,*p2; p1=&p1; p2=&p2;
Address + Number = Address (Next Address) Address – Number = Address(pre Address) Address ++=Address(Next address) Address--=Address(Pre Address) ++ Address= Address(Next Address) --Address = Address(Pre address)
Address – Address = Number(No.of elements) = size diff/sizeof(datatype) int*p1=(int*)100; int*p2=(int*)200; p2-p1=50 200-100 ------- > 100/size of(int)
Address + Address=Illegal. Address * Address= illegal Address/Address= illegal Address%Address=illegal
We can use relational operator and conditional operator b/w two pointers(<,>,<=,>=,==,!=,?!) Address > Address = T/F Address > = Address = T/F
We can’t perform bitwise operation b/w two pointers like Address & Address = illegal Address | Address=Illegal Address ^ Address = illegal ~ Address=illegal
We can find the size of a pointer using the size of the operator.
