"Guess my Number" game in C++
a few remarks:


Use int instead of unsigned short
Don't use Hungarian naming ('kusi/usi' prefix) - nobody uses that.
Add argc/argv parameters to main
Dont import everything from std with using namespace std
Add spaces around operators (=, != , ==, >>, &lt;&lt; etc) and after 'while', 'if' etc.
You have carefully used constants for the high/low boundaries, but your print statements  don't use these constants ("Guess a number between 1 and 100:")
