I want to know if it is possible to change case 1, 2etc... to letter or even word choices? Example: Zork, Dungeon choises...
Also, how do you tell your program to remember cin codes throughout the program, such as a name or item?

[JackOfAllTrades]

Letter yes, word no. cases in a switch statement must be integers (character are actually integers...check out an ASCII table).

Are unsure of the cin question?

[stayscrisp]

Giving someone a choice of numbers is much easier than getting them to type in a word and then comparing it. As for your other question, when you declare pickRace and then it gets set to whatever is passed in from std::cin it will stay at that value until you change it, you can then use it further into the program. You might want to just rename it to playerRace.

Another option is to create an array of strings that hold the different races as strings.

std::string raceNames[3];
raceNames[0] = "Human";
raceNames[1] = "Orc";
raceNames[2] = "Elf";

int playerRace = 0;

std::cin >> playerRace;

// user inputs 3, playerRace is now 3 an elf

void printPlayerStats()
{
    std::cout << "Player stats\n\n";
    std::cout << "Name: " << userName << "\n";
    std::cout << "Race: " << raceNames[playerRace - 1] << "\n";
}

// etc etc

you might also think about making player a class or a struct and holding the data in there.

Hope that helps some

When I close one and open another it states that the cin >>Eample>> is undeclared although it is used before...
I am confused...

You want it to remember the data after you close the application?

Yes and no but what I meant to say was after I close one function and start another it "forgets" the cin hence the undeclared message...

[stayscrisp]

This is because variables only exist in the scope they are created. For example if you create a variable inside a function then it will only exist inside that function. If you wish to use variables in different functions then you have a few choices.

You could use global variables

#include <iostream>
int global = 0; // a global variable

void setGlobal()
{
    global = 10;
}

void printGlobal()
{
   std::cout << global;
}

int main()
{
    setGlobal();
    printGlobal();

    return 0;
}

Or you could do what I previously suggested and make your player data into a struct

#include <iostream>

struct Player
{
    int race;
    std::string userName;
};

void printPlayerStats(Player* player)
{
    std::cout << "-- Player Stats --\n\n";
    std::cout << player->race << "\n";
    std::cout << player->userName << "\n";
}

void changePlayerStats(Player* player)
{
    player->race += 1;
    player->userName = "newUser";
}

int main()
{
     Player thePlayer; // create an instance of your player struct

     thePlayer.race = 1;
     thePlayer.userName = "Bob";

     printPlayerStats(&thePlayer);
     changePlayerStats(&thePlayer);
     printPlayerStats(&thePlayer);

     return 0;
}

This is a much better option because global variables are hideous. http://c2.com/cgi/wi...VariablesAreBad

This is actually not right; switch expression must be integral types. This means a switch can handle char, int, bool, short and long, but not float.


More importantly however, switch can work with enum types, which is exactly what you want here.


An enum(eration) can be thought of as a single variable with a fixed set of ( behind the scenes numeric ) values. Therefore what you can do is declare:

enum Races { 
Human = 0,
Elf,
Troll,
Goat, 
French };

Then in your switch you can use:

player.Race = Human;
...

....

switch(player.Race)
{
 case Human:
   DoHumanStuff();
   break;
 case Elf:
   DoFairyWussyStuff();
   break;
 case French:
   FaireDesChosesFrançaises();
   break;
 default:
   DoNothing();
}

Enums are inititally confusing, but in the end, are exactly what you want.


This coincidentally is one of those things that makes C# much more appropriate for new developers, in C# you could simply do:

string race = "Human";
switch(race.toLower())
{
  case "human":
    DoHumanStuff();
}

Vastly easier to comprehend, although an order of magnitude slower.

This depends on what the OP wants to achieve. My impression is that he wants a user to be able to input a word to choose their race, enums would not help to achieve this. The only thing using enums would improve is code readability.

Also, JackOfAllTrades is right. All of the types you mentioned are in fact integers. Integral types are integers, at least where c++ is concerned.

All of which are, in fact, integers at their core.
