C++ Hints

by PVS-Studio Team

From the hint:

Although the code is neat and easy-to-read, it didn't prevent the developers from overlooking the error. You can't stay focused when reading code like that because all you see is just similarly looking blocks and you can't help just quickly scanning through them. These similar blocks have most likely resulted from the programmer's desire to optimize the code as much as possible. He or she just "unrolled the loop" manually. I don't think it was a good idea in this case.
