displaying enums

[Aaron Toponce]

Okay, maybe this is a dumb question, but here it goes: Consider the
following code:

enum day_of_week {Mon = 1, Tue, Wed, Thu, Fri, Sat, Sun};

Now, we all know that enums positions are looked at as integers, how would
one go about displaying say "Mon" rather than "1"? For example consider
some more code:
#include <iostream>
#include "stdlib.h"
using namespace std;

enum day_of_week {Mon = 1, Tue, Wed, Thu, Fri, Sat, Sun};

int main()
{
int iChoice;

cout << "Enter a number representing it's corresponding day of the week:
"; cin >> iChoice;
cout << "Your day is " << // what would I type here to access the
corresponding place in day_of_week?

system("PAUSE");
return 0;
}

Thanks for your help

You are assuming agreement that Monday is the first day of the week, by the
way (some people would say that Sunday is).

You wouldn't.

Enums don't provide strings. Use an array of strings or something instead.

It exists a solution that you'll obtain searching with keywords
"C++ enum to string" into Google groups (sorry, I don't know how to have
the URL of the answer), a posting on june 16 2003.

It proposes you writing someting like:
//##markup##"enum DAY_OF_WEEK"
//##data##
//Mon
//Tue
//Wef
//Thu
//Fri
//Sat
//Sun
//##data##

and a code generator easy-to-use writes both the enum definition and the
function 'std::string DAY_OF_WEEKToString(DAY_OF_WEEK e)' for you in your
code.

Note that a small improvement should be brought to take into account the
assignment of a value to the enum.
