to deal with this you should read the data from the user AS a string. It will go nuts if you read it as an integer.
then convert the string to integer with your favorite tool, stoi() is one of the choices.
validation is on you, stoi isnt too smart so you can check all the input string for isdigit()s or whatever validation you want to do.
Extracting data from std::cin using formatted extraction (operator>>) is not easily error proof when retrieving numeric data, it is all too easy to break it.
A bit of a read, but worth the time to learn how to cut down on problems with getting numeric data from users who have fat fingers and are trying to break your code.
@OP
The attached several snippets show a couple of ways of handling user input errors. None of it is a simple catch all or quick fix. For instance someone 'could' conceivably have a name "1234" but an integer AbcZ.9 is neither an integer nor a float/integer or any other conceivable orthodox numerical value.
The nearest catch all in some instances is to get the user to verify their input.
