Returning Strings

How do I return a string from a function? The only way I know how to use strings are character arrays, but how would you declare a function to return a character array?

yuo return a pointer to a character array or include

Code:

---

#include<string>

---

in your code and you may use "string" as a type. e.g. string myString

1. do I need to include any header files for string types?
2. is this considered okay in context to the information you just gave me:

Code:

---

string convert_enemy(int enemy)
{
    switch(enemy)
    {
    case 1: return "Rabid Wolf";
            break;
    case 2: return "Bear";
            break;
    etc.
    }
}

---

just to show you what ryan is talking about

Code:

---

#include <iostream>
#include <string>
using std::string;
using std::cout;
using std::cin;
string creturn()
{
  string letters="hello";
  return letters;
}

int main()
{
  string print=creturn();
  cout<<print;
  cin.get()
  return 0;
}
//btw: isn't the string class nice :)

Omg! Is it legal? :D I mean.. is it standart?

Yeah, it is :)

(at least.. there isn't anything nonstandard that I see with it)

Really? Then please explain me why there is no that method in most books? And why most tutorials in internet using character arrays instead of this so-handy method?

umm i don't know the string class is really easy to use and its completly standard. Most tutorials are a bit out of date still very usefull but a little old

Because you're reading about C, not C++ possibly?

Oh, and Overload, I think that you'll need to return like this:

Code:

---

#include <string>

using namespace std; // for our purposes, you can just make this 'using std::string;', otherwise you'll have to use std::string all the time

string convert_enemy(int enemy)
{
    switch(enemy)
    {
    case 1: return string ("Rabid Wolf");
            break;
    case 2: return string ("Bear");
            break;
    etc.
    }
}

//EDIT: Holy sheet is it just me, or is my user info column messed up?

I may have been wrong. But a lot of books specify you can make functions with any return type. I'll let someone else answer the rest :)

Ok, its clear.

Its not you or your column. Its forum bug :\ I have the same in previous post.

Its not your user collum you just posted a really long comment so the thing is adjusting for it

Code:

You shouldn't need to return an explicit string. An implicit conversion will be made for you. I tested it both ways under the MSVC++ 6.0 environment and they both work.

Oh okay, thanks for the clarification.

I realise how it's "adjusting" to my post, but it's really ugly and would be nicer if it just stayed the same :rolleyes:

yea, cuz my reasoning behind was because I dont write:

return int (0);

:p

P.S. FYI cuz i'm just a smart ass like that, Tman you quoted the wrong person. :rolleyes:
