Thread: switch case question

Got a question. Can the switch-case statement be used with characters(char) inputs?
code:

Code:

switch (choice)
	{
	case ('A'||'a'):
		break;
	case ('S'||'s'):
		break;
	case ('M'||'m'):
		break;
	case ('E'||'e'):
		break;
	case ('N'||'n'):
		break;
	default:
		printf("\aError incorrect selection!!!\n");
	}

choice is a user input value that is read from a function. I'm sure that the character is being returned properly from the function, I've used printfs to test it. Here is the error:

\Group_R03.cpp(30) : error C2196: case value '1' already used
.\Group_R03.cpp(32) : error C2196: case value '1' already used
.\Group_R03.cpp(34) : error C2196: case value '1' already used
.\Group_R03.cpp(36) : error C2196: case value '1' already used

it looks as it it setting a value of one to all the cases. I'm alittle confused. thanks in advance for any feedback!
