What's the difference between char and int in a switch case?

Using char or int are both ok in a switch statement. It depends on how you input your Fav_Car - as long as the input matches with a case, that case will be executed.

Note that char is also an integral type - it has a value in range [32, 127] (assume you want a printable char).

what's the difference if I use case '1' : and case "1"

switch case only work with integral (ie int, char). So:

case '1':   // ok.

case "1":   // wrong because "1" is a string - not integral type.
