For ex : If we want to multiply (8 * 9) then we can left shift 9 by 3 as 8 is 2^3. We can consider any operand of the expression in case of multiplication but in case of division the denominator should be a multiple of 2 then only we can do the operation by right shifting the numerator.
For ex : If we want to divide (8 / 9), denominator (9) must be multiple of 2. Here we can not do this operation. But if we want to divide (9 / 8), now denominator (8) is a multiple of 2. Hence we can do the same operation by right shifting the numerator (9) by 3.
(8 * 9) == (9 << 3) and (9 / 8) == (9 >> 3)
You can do modulo operation as mentioned below :
Ex : (15 % 2) == (15 & 1), (16 % 8) == (16 & 7)
Note : Bitwise operators only works with integer type variables. (Ex : int, u_int, char, u_char, short)
