Today, let’s take a short test. Find what is likely to be a bug in the following code and suggest how to fix it. You may object to thus stated task. We only see a small portion of the code. … Continue reading
Update. One of the readers informed me that the same problem has been already described by R. Martinho Fernandes (see here), Eric Niebler (see here) and Scott Meyers (see here); so I should at least link to their articles. Now … Continue reading
