Count Set Bits
C Program to count the set bits:
Multiples of 8
To check if the number is multiple of 8, the bitwise way is that: first right shift by 3 and then left shift by 3. Multiple of 8 will remain the same as original number after this operation. Examples: 8: 1000 >> 3 : 0001 <<3 : 1000 24: 11000… Continue reading Multiples of 8
2’s Complement – C Program
We can obtain 2’s complement in atleast two ways through a C program. If n is a number then -n will give the result. The next approach is to first flip all the bits (1’s complement) and then add 1. The bits can be flipped using ~ operator. The program below demonstrates both the approaches.
Check if Number is Odd Using Bitwise – C
An odd number always has the LSB set to 1. If we AND the given number with 1, the even number will always turn out to be zero. We can using this to check if the number is odd or even. Examples: 1) n = 4 100 (4) 001 (1) ———– AND 000… Continue reading Check if Number is Odd Using Bitwise – C

Case Conversion using Bitwise – C
We generally use the functions strlwr() and strupr() available under string.h to toggle between the cases. This can also be achieved using bitwise operations. Before that, lets understand the ASCII table. ASCII of A is 65 (1000001) ASCII of a is 97 (1100001) Similarly, ASCII of Z is 97 (1011010) ASCII of z is 122 (1111010)… Continue reading Case Conversion using Bitwise – C
