| | Another newbie question here. What's the difference between these two? [CODE]cin.ignore(cin.rdbuf()->in_avail(), '\n'); cin.ignore(numeric_limits<streamsize>::max(), '\n');[/CODE] I understand that the former will ignore only the characters [I]left[/I] in the stream buffer, while the latter tries to ignore characters equal to the [I]size[/I] of the buffer. So the end result should, normally, be … |
