value of i is increasing (i++) while value of k is decreasing (k-- in condition)...Values are as under s.no. i k 1 0 9(k--) 2 1 8 3 2 7 4 3 6 5 4 5 6 5 6 (this violates the condition i<k--) hence the statement is printed 5 times.

I do not like Java.

Solve it with a table if you need:

i, k, bool

0, 10, 1

1, 09, 1

2, 08, 1

3, 07, 1

4, 06, 1

5, 05, 0

There are 5 (true) evaluations for i < k--.

no operation on k.....so it will remain 10 through out the procedure...so ans should be 8...!!

absolutely wrong! the correct answer should be 10! the value of k doesn't change ...... since no operation is performed with "k" itself.
i<k-- only checks the value of "k"........ doesn't change it!

there is a post decrement opearator after k (k--)...so with every iteration of the loop k's value decreases.....so answer will be 5

k-- executes k=k-1 on the statement, thus everytime the cycle runs an iteration k=k-1
