Using char in a switch

[kultrva]

How do you use a variable type char in a switch statement?
Below is a segment of code that I'm working on. Can anybody tell me how to fix it?

void getMoreFunds(int &balance)
{
	char answer;

	cout<<"Would you like to replenish your funds? (y/n)";
	cin>>answer;

	switch (answer){
	case "y":
		balance += 50;
		cout<<"Your balance is now "<<balance<<"."<<endl;
		break;
	case "n":
		break;
	default:
		cout<<"Invalid response"<<endl;
	}
}

Also, I'm not sure if that is the correct usage of a reference parameter... Could somebody tell me if I'm on the right track there as well?

Thanks in advance to anybody who can help me!

Use single quotes for character literals
