1) You don't need to use scanf in C++, you can use cin
2) You should read all data in as a string (preferably an ANSI C++
string and not a char * ) and then validate the data, converting as
necessary to the appropriate data type.
3) I personally don't like to use try-catch to handle data input
errors, you should use proper data validation. try-catch should be
used for exceptional situations, like disk out of space or a network
socket has closed upexpectedly or something along those lines.
