compiler required: visual studio 2019
and do not use #include <bits/stdc++.h>
Change the database.cpp program to throw exceptions when there
is an unexpected problem (wrong database name, wrong and record size not
in the range listed, puts in letter instead of number, more other possibilities) and
when appropriate offer the user an option to fix the problem. In case there is
a problem, you are supposed to throw an exception (and of course catch it) and
then possibly allow the user to correct the error.
