bitwise operators in c code example

Example 1: bitwise operator

bitwise complement of N = ~N (represented in 2's complement form)
2'complement of ~N= -(~(~N)+1) = -(N+1)

Example 2: bitshift c

i = 14; // Bit pattern 00001110
j = i >> 1; // here we have the bit pattern shifted by 1 thus we get 00000111 = 7 which is 14/2

Example 3: bitwise operator

12 = 00001100 (In Binary)
25 = 00011001 (In Binary)

Bit Operation of 12 and 25
  00001100
& 00011001
  ________
  00001000  = 8 (In decimal)

Example 4: C bitwise

#include <stdio.h>
int main(void) {
  unsigned int a = 60; //Equal to: 0011 1100
  unsigned int b = 13 // Equal to: 0000 1101
  
  int both = a & b //If both are 0, then its a 0, 
  // if both are 1, then its a 1.  //0000 1100
  
  printf("%d\n", both);
