C# Language: Changing the First Four Bits in a Byte

Question

In order to utilize a byte to its fullest potential, I\'m attempting to store two unique values into a byte: one in the first four bits and another in the second four bits. How

Answer 1

Assuming newVal contains the value you want to store in origVal. Do this for the 4 least significant bits:

byte origVal = ???;
byte newVal = ???
orig = (origVal & 0xF0) + newVal;

and this for the 4 most significant bits:

byte origVal = ???;
byte newVal = ???
orig = (origVal & 0xF) + (newVal << 4);
