The use of unsigned int

[Paul Siu]

The most commonly use, and commonly returned type in C is probably int.  
In some cases, wouldn't it be more appropriate if unsigned int was used
instead, such as when you are indexing an array, or returning a length?

I heard that int is usually declared as the most efficent type in C, would
using unsigned int cause any problems such as slow things down or cause
type-conversation problems?
