Double Checking the Answer

Good evening everyone.

I came up with the answer 25 for the below question/code. Since J is holding the value of 0 and k = 50, k is greater than 0 thus j + k = 50 and k / 2 is 25. Am I in the ballpark or am I still out in the parking lot on this one?

Let j and k be two int variables. Trace the execution of the following for loop by showing the values of j and k at the end of each iteration (i.e., immediately after the update part is executed):
for (j = 0, k = 50; k > 0; j += k)
k /= 2;

You're okay on the first iteration. Also, remember how Java rounds (it truncates decimals since k is an int).

Variable j accumulates the values of k after the loop body has executed and while
k > 0, so at the end k ends up to be zero because it is divided by two repeatedly
and j= 12+6+3+1+0

kind regards,
