Thread: returning a string?

I've basically been playing with C++ more and more recently and one thing i've came accross is returning a string?

I tried to declare it in my header file while doing the prototypes and the VS .NET doesn't seem to like it, it was fine when i was using char but now i need to return two characters.

i included the string library so i'm now puzzled.

Code:

#include <string>
using namespace std;

string convert_num(int cnumber) {
	string temp;
	cnumber = (cnumber%13);
	switch (cnumber) {
		case 0:
			temp = 'K';
			break;
		case 1:
			temp = 'A';
			break;
		case 2:
			temp = '2';
			break;
		case 3:
			temp = '3';
			break;
		case 4:
			temp = '4';
			break;
		case 5:
			temp = '5';
			break;
		case 6:
			temp = '6';
			break;
		case 7:
			temp = '7';
			break;
		case 8:
			temp = '8';
			break;
		case 9:
			temp = '9';
			break;
		case 10:
			temp = '10';
			break;
		case 11:
			temp = 'J';
			break;
		case 12:
			temp = 'Q';
			break;
		default :
			temp = 'K';
			break;
	}
	return temp;
}

and in the head file

Code:

string convert_num(int cnumber);

and yes it is the customary blackjack game that everyone gets asked to do.
