bitwise and code example

Example 1: bitwise operator

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

Bitwise XOR Operation of 12 and 25
  00001100
^ 00011001
  ________
  00010101  = 21 (In decimal)

Example 2: bitwise operator

#include 
int main()
{
    int a = 12, b = 25;
    printf("Output = %d", a&b);
    return 0;
}

Example 3: bitwise operator

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

Example 4: bitwise operator

#include 
int main()
{
    printf("Output = %d\n",~35);
    printf("Output = %d\n",~-12);
    return 0;
}

Example 5: ;bitwise

#include 
int main()
{
    int a = 12, b = 25;
    printf("Output = %d", a^b);
    return 0;
}

Example 6: bitwise operator

Decimal         Binary           2's complement 
   0            00000000           -(11111111+1) = -00000000 = -0(decimal)
   1            00000001           -(11111110+1) = -11111111 = -256(decimal)
   12           00001100           -(11110011+1) = -11110100 = -244(decimal)
   220          11011100           -(00100011+1) = -00100100 = -36(decimal)

Note: Overflow is ignored while computing 2's complement.
