Hey Vatsav
prefix (--i) decrement 1 from " i " , and any non-zero value is true value for conditional expression , so it print 5,4,3,2,1 and at 0 it becomes false so terminates !

If it was i++ or ++i then it can make upto infinity
You can see the above explanation for your understanding.
+ 1
its a prefix expression. examples:
i++
i--
--i
++i
the first couple, increments/decrements the variable after loop completes
the second couple increments/decrements before the variable is read
