C Operator Practice

Task1: Bits operator

#include <stdio.h>

#define PRINT (int) printf (#int "=%d\n", int)

int main (void)

{

int x,y,z;

/*

*/

x = 03; y = 02; z = 01;

PRINT (x | Y & Z); 0011 | 0000 = 3

PRINT (x | Y & ~ z); 0011 | 0010 = 3

PRINT (x ^ y & ~ z); 0011 ^ 0010 = 1

PRINT (x & y && z); 2 && 1 = 1

x = 1; y =-1;

PRINT (! x | x); ((!x) | x) =false | x = 1

PRINT (~ x | x); 1111 =-1

PRINT (x ^ x); 0001 ^ 0001 = 0

x <<= 3; PRINT (x); The left-shifted n-bit effect is considered multiplied by n 2 = 8

Y <<= 3; PRINT (y); ... &hellip------------------------8

Y >>= 3; PRINT (y); Right shift n-bit effect as divided by n 2 =-1

return 0;

}

Output results:

x | Y & z = 3

x | Y & ~ z = 3

x ^ Y & ~ z = 1

X & y && z = 1

! x | x = 1

~ X | x =-1

x ^ x = 0

x = 8

y =-8

y =-1
