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

Are you sure that INT is not working?

The following code works well:

#include 

int main() {
    int fav_car = 2;
switch(fav_car) {
        case 1 :
            std::cout<< "That's cool";
        break;
        case 2 :
            std::cout<< "Even mine!";
        break;
        default :
            std::cout<< "Oh";
        break;
    }
}

case '1' - it is a symbol

case "1" - it is a string constant
