C++, Switch, input validation

[Brad]

I have a program that has a menu that uses "switch". The input is supposed
to be an integer (1-6). Everything works fine if the user inputs 1-6.
BUT,
it falls into an infinite loop if the user inputs anything else. Is there
a
simple solution or uder-defined function that can be added to validate the

user input (even if mulitple characters or integers)?

To validate input, read the data as a string and then check it to see
that it's valid. To solve the switch problem, insert a default case:

switch(x)
{
case '1':
break;
//...
case '6':
break;
default: // handle all other cases
break;
}
