cin.ignore()

hello, why everybody puts `cin.ignore()` after a `cin >>`. Some people say that cin can leave a terminating character in the stream. Well, i didnt understand that. What problems can it origin? give examples, please..

You mean `cin>>cin.ignore();` ? Hell if I know, that makes no sense.

No, i mean, for example you have an integer x. you do:

1 2

cin >> x;
cin.ignore();

Everybody use this, and i dont know why...

cin leaves the newline character in the stream. Adding cin.ignore() to the next line clears/ignores the newline from the stream. This is used mainly with combinations of cin and getline. I can't think of any examples but over time you will find them if you use getline and cin together. Take a look at this: http://www.cplusplus.com/forum/articles/6046/

`ignore()` will flush the input stream, just like C `fflush(stdin)`, which is great for removing the annoying new lines stored at the end of the stream :P
