Oh, I guess you are right. Standard doesn't specify behaviour for cin's
streambuf type. It is implementation-specific. It worked for me on different
platforms and compilers. I was also reading it's definition on cplusplus.com
but I should look what standard says.
Anyway, it would be nice if it worked as I expected. cin.ignore() statements
inside loops could be avoided.
Thank you for your fast reply.
