Do you (really) write exception safe code? [closed]
...boost.org/community/exception_safety.html
Look at the 7th point (Automated testing for exception-safety), where he relies on automated unit testing to make sure every case is tested. I guess this part is an excellent answer to the question author's "Can you even be sure, that it is?".

O(nlogn) Algorithm - Find three evenly spaced ones within binary string
I had this question on an Algorithms test yesterday, and I can't figure out the answer. It is driving me absolutely crazy, because it was worth about 40 points. I figure that most of the class didn't solve it correctly, because I haven't come up with a solution in the past 24 hours.

Swapping two variable value without using third variable
...rent
*x ^= *y;
*y ^= *x;
*x ^= *y;
}
}
Why the test?

echo Delete me > delete-me
git add change-me...
