Bit operations in c++
WebJan 31, 2024 · Efficient Approach: Use bit manipulation in order to find the quotient. The divisor and dividend can be written as . dividend = quotient * divisor + remainder. As every number can be represented in base 2(0 or 1), represent the quotient in binary form by using the shift operator as given below: Determine the most significant bit in the divisor.

WebApr 4, 2024 · c) “-=”. This operator is a combination of ‘-‘ and ‘=’ operators. This operator first subtracts the value on the right from the current value of the variable on left and then assigns the result to the variable on the left. (a -= b) can be written as (a = a - b) If initially value stored in a is 8. Then (a -= 6) = 2. WebNov 9, 2024 · Thanks to Utkarsh Trivedi for suggesting this solution. A Better Solution can find XOR without using a loop. 1) Find bitwise OR of x and y (Result has set bits where either x has set or y has set bit). OR of x = 3 (011) and y = 5 (101) is 7 (111) 2) To remove extra set bits find places where both x and y have set bits.
