Question

PLEASE SHOW ME YOUR WORKS
Imagine that the bits are numbered as:

B7 B6 B5 B4 B3 B2 B1 B0
-------------------------------
| 0 | 1 | 0 | 1 | 1 | 0 | 1 | 0 |
-------------------------------


[Part A] If you wanted the Bits B4 and B3 to define a new variable,
how would you manipulate the above byte (called NUM). Hint: apply
a bitwise AND and a shift.


[Part B] Write the code for checking if Bit B6 is set?



[Question 12]


flag1 = 10101110
flag2 = 01101010
flag3 = 11101101

mask1 = flag1 & flag2 & flag3

mask2 = (flag1 | flag2) & flag3

mask3 = (flag1 & flag2) | flag3

Write your answer in binary:

What is the result of mask1?

What is the result of mask2?

What is the result of mask3?

Explanation / Answer

please rate - thanks [Part A] If you wanted the Bits B4 and B3 to define a new variable,
how would you manipulate the above byte (called NUM). Hint: apply
a bitwise AND and a shift.
------------------------------- flag1=00011000 newnum=num&flag1
newnum=numnum>3    (shift newnum 3 bits to the right) mask1 = flag1 & flag2 & flag3        mask1=00101010 mask2 = (flag1 | flag2) & flag3      mask2=11101100 mask3 = (flag1 & flag2) | flag3      mask3=11101111
