May B U need to fflush the standard input prior to getting input from user through cin.

You need to use cin.clear() and cin.ignore() to clear errors and discard unwanted items in the stream.

They are documented as part of istream (http://www.cplusplus.com/reference/iostream/istream/), and also in several older answers on this forum.

This question pos up reasonbly frequently - Grey Wolf do you fancy adding another of your excellent articles on this?
