Best Variable to Use

[Paul McKenzie]

I have a data that can only be one of two values. They are strings, say "black" and "White".

I was thinking of just using the string type, but then I thought it might be better to use a bool since the value can take only one of two values.

You can have both. This is just off the top of my head without putting a lot of thought into it:

#include <map>
#include <string>
#include <iostream>

typedef std::map<bool, std::string> BoolMap;

using namespace std;

int main()
{
   BoolMap myMap;
   // Initialize the map
   myMap.insert(make_pair(true,"White"));
   myMap.insert(make_pair(false,"Black"));

   // Prove it works
   cout << "The value of true is " << myMap[true] << "\n";
   cout << "The value of false is " << myMap[false];
}

I'm sure others will add alternatives to the above.
