Bit Manipulation
We reviewed bitwise logical operations in C (&=AND, |=OR, ^=XOR):
A = 0011 1100
B = 0000 1101
---------------------
A&B = 0000 1100
A|B = 0011 1101
A^B = 0011 0001
For the following three questions, assume:
A = 1010 1010 1010
B = 0000 1111 0000
And compute the results of these bitwise operations:
(A & B)& B 1 Answer:
(A | B)| B 2 Answer:
(A ^ B)^ B 3 Answer:
We also discussed the C shift operations (shift left=<< and shift right=>>). For the following two questions, assume:
C = 0001 1001 1010
And compute the results of these shift operations:
4. C >> 3 4 Answer:
5. C << 2 5 Answer:
A group of eight bits is called a(n) _______________.
