Write a function to perform a bitwise AND, OR, and XOR on two integers and perform a bitwise NOT on the first number.

C

void bitwise(int a, int b)
{
  printf("a and b: %d\n", a & b);
  printf("a or b: %d\n", a | b);
  printf("a xor b: %d\n", a ^ b);
  printf("not a: %d\n", ~a);
}

Java

public static void bitwise(int a, int b){
  System.out.println("a AND b: " + (a & b));
  System.out.println("a OR b: "+ (a | b));
  System.out.println("a XOR b: "+ (a ^ b));
  System.out.println("NOT a: " + ~a);
}

The call:

bitwise(4, 7);

will output:

a AND b: 4
a OR b: 7
a XOR b: 3
NOT a: -5
