Thread: Strings and Switch Statement

i'm having a problem with a switchstatement that uses strings as the argument and it looks something like this

Code:

void Game(Game Info,ifstream &fin)
{
	int b,c;
	string a;
	OpenRoom(Info,fin);
	cin>>a;
	while (a!="quit" || a!="exit")
	{
		switch (a)
		{
		case "remove":
			Remove(Info,fin);
			break;
		case "epuip":
			Equip(Info,fin);
			break;
		case "quit":
			break;
		case "northwest":
			Go(Info,fin,5);
			break;
		case "southwest":
			Go(Info,fin,7);
			break;
		case "nw":
			Go(Info,fin,5);
			break;
		case "sw":
			Go(Info,fin,7);
			break;
		case "northeast":
			Go(Info,fin,4);
			break;
		case "southeast":
			Go(Info,fin,6);
			break;
		case "ne":
			Go(Info,fin,4);
			break;
		case "se":
			Go(Info,fin,6);
			break;
		case "w":
			Go(Info,fin,3);
			break;
		case "e":
			Go(Info,fin,2);
			break;
		case "s":
			Go(Info,fin,1);
			break;
		case "n":
			Go(Info,fin,0);
			break;
		case "north":
			Go(Info,fin,0);
			break;
		case "east":
			Go(Info,fin,2);
			break;
		case "west":
			Go(Info,fin,3);
			break;
		case "south":
			Go(Info,fin,1);
			break;
		case "pick":
			cin>>a;
			switch (a)
			{
			case "up":
				Get(Info,fin);
				break;
			case "nose":
				cout<<"Thats really sick.\n";
				break;
			}
			break;
		case "get":
			Get(Info,fin);
			break;
		case "help":
			cout<<"While this function of the game is not yet complete, it does have a few tips.\n";
			break;
		case "drop":
			cin>>a;
			Drop(Info,fin);
			break;
		case "save":
			SaveGame(Info,false);
			break;
		case "Loki":
			Loki(Info);
			break;
		case "Dogma":
			Dogma(Info);
			break;
		case "buy":
			Buy(Info,fin);
			break;
		default:
			Error(24);
		}
	}
}

all of the functions are defined it just gives me an error for every line about a constant i'm using microsoft visual studio .net 2003 and visual c++ pro 6.0. if any one has any thoughts they would be apreciated.

Code Tags added by Kermi3

the actual error is

c:\documents and settings\alli-poo\my documents\visual studio projects\c++\ffec.cpp(471) : error C2051: case expression not constant

Sry bout the Code tags i forgot and thx for the input about the switch statement i didn't know that....

You may want something like this:

Code:

std::string Command;
if(Command == "North")
{
   ...
}
else if(Command == "South")
{
   ...
}
else if ...
