A Newbie's question in C++

Hi,
Well this is very simple program. But it isnt working. Giving me three errors when compiled using VC++. However i compiled the same program with borland C++ and i didnt get any errors.

Code:

---


#include <iostream.h>
#include <string.h>

int main()
{
        string userName;

        cout << "What is your Name? ";

        cin >> userName;

        cout << "Hello " << userName << "!" << endl;

        return 0;
}

---

The errors are as follows

--------------------Configuration: hello3 - Win32 Debug--------------------
Compiling...
hello.cpp
C:\Workspace\Practise\hello3\hello.cpp(6) : error C2065: 'string' : undeclared identifier
C:\Workspace\Practise\hello3\hello.cpp(6) : error C2146: syntax error : missing ';' before identifier 'userName'
C:\Workspace\Practise\hello3\hello.cpp(6) : error C2065: 'userName' : undeclared identifier
Error executing cl.exe.

hello3.exe - 3 error(s), 0 warning(s)

Please help

Code:

---

#include <iostream>
#include <string>
using namespace std;
int main()
{
        string userName;

        cout << "What is your Name? ";

        cin >> userName;

        cout << "Hello " << userName << "!" << endl;

        return 0;
}

Use C++ style header's when coding C++.

Try to avoid the old <*.h> headers and opt for the the namespace safer headrers...like so.

Code:

---

#include <iostream>
using std::cout;
using std::cin;
using std::endl;
#include <string>
using std::string;

int main()
{
string userName;

cout << "What is your Name? ";

cin >> userName;

cout << "Hello " << userName << "!" << endl;

return 0;
}

Doh......

Sorry Adrian.......you beat me this time :)

Thanx:D

>>> Sorry Adrian.......you beat me this time

Ah yes, but our solutions did show both ways of resolving the namespace!

Ruflano's way is always the better way.


#include <iostream.h>
#include <conio.h>
#include <conio.c>

int age(0);
char username[30];

int main()
{
textcolor( 1 ); //love to show off
cout << "Type in your username punk: " << endl;
cin >> username;
cout << "\nHi " << username << ". How old are you?" << endl;
cin >> age;

cout << "\nSo, you're " << age << " years old and your name is " << username << ". Thats sad" << endl;
getch();
return 0;
}

>>> Ruflano's way is always the better way.

Hmmm.

>>> #include <iostream.h>

Ah, one of the problems he was having...

>>> #include <conio.c>

Including a .c file, hmmm.

>>> textcolor( 1 ); //love to show off

Non standard, won't work with VC++, (i.e. what he was asking about).

>>>
cout << "\nSo, you're " << age << " years old and your name is " << username << ". Thats sad" << endl;
getch();
<<<

Mixing traditional C I/O with C++ stream I/O. An endless source of difficult to debug problems.
