functions won't work

before i explain my problem i'll give you what i've got so far

Code:

#include <windows.h>
#include <iostream>

using namespace std;
 int question ( string usr_name );
int main()
{
string usr_name;
cout<<"hello enter a name: ";
cin>> usr_name;
cin.ignore();
cout<<"ok so your name is "<< question ( usr_name );
Sleep (20000);
}

int question ( string usr_name )
{
  return usr_name;
}

now as you can probably gather i'm trying to make a function out of the code above and i think i've got it but when i compile i get an error on the

Code:

 {
  return usr_name;
}

part of it, i've scanned tutorials but i can't find my problem or how to solve it, i realize this is probably some basic problem involving a misplaced semicolon or somethiing but i'd appreciate it if someone can help me out with the problem anyhow. thanks in advance

int question ( string usr_name )
Well you pass it a string, and try and return an int.
Make the types compatible.

eg, make question() return a string.

BTW, you should include <string> if you're going to be using strings.

Actually, <iostream> includes <string> for many of it's functions, so it's not really necessary.

You mean your iostream includes string.
Other people's compilers may not have the same internal dependencies.

Many people have complained that cout << myString doesn't work when myString is a string and they end up using cout << myString.c_str(). The source of there error is not including <string>. That is because at least one popular compiler library includes only parts of <string> inside <iostream>.

Never rely on one header including another header, always explicitly include any header that you need in your file.
