- 2. • Bitwise Operators To be covered 2
- 3. Bitwise Operator Bitwise operator permit programmer to access and manipulate of data at bit level. Various bitwise operator enlisted are • One's complement (~) • Bitwise AND (&) • Bitwise OR (|) • Bitwise XOR (^) • Left shift (<<) • Right shift (>>) These operator can operate on integer and character value but not on float and double.
- 10. Assume if A = 60; and B = 13; now in binary format they will be as follows: A = 0011 1100 B = 0000 1101 ----------------- A&B = 0000 1100 A|B = 0011 1101 A^B = 0011 0001 ~A = 1100 0011 A<<2 = 1111 0000 A>>2 = 0000 1111 Bitwise Operator (Example)
- 11. main() { unsigned int a = 60; /* 60 = 0011 1100 */ unsigned int b = 13; /* 13 = 0000 1101 */ int c = 0; c = a & b; printf("Line 1 - Value of c is %dn", c ); c = a | b; printf("Line 2 - Value of c is %dn", c ); c = a ^ b; printf("Line 3 - Value of c is %dn", c ); c = ~a; printf("Line 4 - Value of c is %dn", c ); c = a << 2; printf("Line 5 - Value of c is %dn", c ); c = a >> 2; printf("Line 6 - Value of c is %dn", c ); } Bitwise Operator (Example)
