How to make function return string in c++

How to convert this code to use string

I have a function like this:

char *foo()
{

}

How can I make it return a string instead? I tried

string foo()
{

}

but the compiler complains.

My advice is to start with Hello World. Clearly you know how to program, but just need to get the compiler working. — Potatoswatter, Sep 25 '10 at 07:44
@sbi, a complaint is a tool for converting code to executable programs? (SCNR either :) ) — avakar, Sep 25 '10 at 10:31

Did you do this:

#include <string>
using std::string;

And additionnally, do you use gcc or g++? Even if gcc now can compile C++ code, it is advised to use g++.

I forgot the using std::string. That was the problem. – node ninja Sep 25 '10 at 08:01

[`-1` for suggesting a using declaration.](http://stackoverflow.com/questions/2879555/c-stl-how-to-write-wrappers-for-cout-cerr-cin-and-endl/2880136#2880136) – sbi Sep 25 '10 at 09:58

this is not like suggesting a using namespace, heh. – Benoit Sep 25 '10 at 10:23
The only thing you did forget is to type "std::" in front of standard library classes/functions. Don't take the habit of "using std::string;" or "using namespace" everywhere. ( especially inside .h header files ) – Nikko Sep 27 '10 at 05:54

Try std::string. Standard features are in the std:: namespace.

std::string foo() 
{ 

}

Be careful with "using" directives, especially in header files. Better take the habit to use std::
