Hello World

This code fails :(

Code:

---

#include <iostream.h>

int main ()
{
  cout << "Hello World!";
  return 0;
}

---

Errors are:

LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16
Debug/fu.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

What am I doing wrongly?

Your project is a Windows Application. You want a Win32 Console Application. So make a new project :)

To create it I just did:

new project --> win 32 console app

Then from file view, right clicked to add a new cpp file.

In the cpp file I added the code then clicked ! to compile it and it bombed.

Can someone tell me why?

I just tried it again and it worked. I must have chosen something other than console app :rolleyes:, thanks for the help.

Ah, that's good, I was about to be very confused ;)

Code:

---

#include <iostream.h>

int main() {
    cout << "Hello World!";
    return 0;
}

Pity iostream.h is deprecated :p

Code:

---

#include <iostream>

using std::cout;
using std::endl;

int main() {
    cout << "Hello World!" << endl;
    return 0;
}

You sometime try to confuse by using...;)

If you require many of iostream's routine, then you can just include the whole namespace.

Code:

---

using namespace std;

---

/* This program says hello world*/
#Include<<iostream.h>>
voidmain(void)
{
cout<<"Hello World!";
}

1. iostream, not iostream.h
2. void main is incorrect. It should be int main. However, the parameters are optional so using void is okay there. You'll need a return statement.

It will works that way, but it will be right if you follow parksie's suggestions.

change

#Include<<iostream.h>>

to

#include <iostream.h>

This is right

Code:

---


#include <iostream>
using namespace std;

int main(int argc, char* argv[])
{
cout<<"Hello World!"<<endl;
return 0;
}
