Cleanest way to combine two shorts to an int

Question

I have two 16-bit shorts (s1 and s2), and I\'m trying to combine them into a single 32-bit integer (i1). According to the spec I\'m dealing with, s1 is the most significant

Answer 1

What you are doing is only meaningful if the shorts and the int are all unsigned. If either of the shorts is signed and has a negative value, the idea of combining them into a single int is meaningless, unless you have been provided with a domain-specific specification to cover such an eventuality.
