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

Question

I started C++ recently and while learning switch case, I got this doubt.
What\'s the difference if I use int or char in the following code :
int Fav_Car;

Answer 1

Characters in switch cases are eventually converted to ASCII equivalent decimal i.e

char '1' - int 49 
char '2' - int 50

For example, if input is integer int 1 , switch case will switch to default because 1 doesn't satisfy any case.

1 != 49
1 != 50

However, in case input is character char '1', output will be the first case as your desire.
