That's expected behavior for the code you wrote.

It's generally recommended to use fgets (followed by sscanf) in such 
cases, not fscanf.  If you must use fscanf, you will have to design your 
format conversion string carefully (for example, include a \n in it), 
and/or look at the value fscanf returns, instead of ignoring it.
