let's say that I have 2 bytes which I've read into int variables:

   int first, second;

how can I turn these two bytes into a single short type variable?

Likewise, how to turn the following 4 bytes (stored in ints again):

   int first, second, third, fourth;

into a single int?

I suck at binary operations, so any explanation to how to do this would be much appreciated.
