Is there an efficient method to achieve the following using binary operations?
First byte : 1001 1110
Second byte : 0001 0011
Desired outcome : 1000 1100
I am looking to reset all bits in the first byte that correspond to bit values of 1 in the second byte.
To achieve this, utilize XOR and AND operators in the following manner:
(A ^ B) & A
Update: Additionally, as suggested by others, you can also employ the AND and NOT operators like so:
A & (~B)
Assuming you have the following variables:
var x = 0x9E;
var y = 0x13;
If you want to achieve your desired outcome, you can use the following code:
var z = x & (~y);
Explanation: By applying the NOT(~) operator to variable y, we create a mask: NOT 0001 0011 => 1110 1100. When this mask is applied to variable x using the AND operator, the bits specified by variable y will be set to 0.
