I guess you use scanf().
Use one or several fgetc() instead.

You simply have to test whether the input was successful. If not, you'll need to clear the error flags on the stream before trying again.

It would help to know if you're using <cstdio> IO (scanf, etc) or <iostream> IO (ifstream, cin, etc).

i used cin.ignore,
cin.clear, cin.fail

In fact just for fun read the entire section 15. This is critical information for all beginners who are writing console applications.
