switch statement issues...(undeclared identifiers)

I am trying to work this switch statement into my future reference program.

Code:

---


char playSong;
    std::cout << "Which is best? La, Da, or This..." << endl;
    std::cin >> playSong;
    switch (playSong){
        case L:
            std::cout << "Lalalalala" << endl;
            break;
        case D:
            std::cout << "Da da da" << endl;
            break;
        case T:
            std::cout << "This love has taken it's toll..." << endl;
            break;
        default:
            std::cout << "Your done." << endl;
            break;
    }

---

The error is saying that L, D, and T are undeclared identifiers...what do I do to solve that?

Quote:

---

case 'L':
std::cout << "Lalalalala" << endl;
break;
case 'D':
std::cout << "Da da da" << endl;
break;
case 'T':
std::cout << "This love has taken it's toll..." << endl;
break;
default:
std::cout << "Your done." << endl;
break;

You need to add ' ' around your letters, otherwise the compiler thinks they are variables.

Thanks, andy.
