c++ compiling errors... very odd!

Hi, my VC++ 6 is acting wierd. After i try running a few small programs, it gives me this error:

--------------------Configuration: a - Win32 Debug--------------------
Linking...
LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16
Debug/a.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

a.exe - 2 error(s), 0 warning(s)

EVEN IF MY PROGRAM IS THIS!

Code:

---

#include <iostream.h>

int main()
{
cout << "Hey";

return 0;
}

---

Use a console project type, not a windows project type.

hm.. works fine after taking your advice.

Few questions though:

- Whats the difference between the 2?
- Why did it work before with WIN32 ?

Thanks!

- Whats the difference between the 2?
console programs start at main()
windows programs start at winmain()

- Why did it work before with WIN32 ?
Huh?

Ah! Ok. But before, when i used WIN32 app, it still worked with this code... but honestly, it really doesnt matter anymore.

I will use console from now on with console applications :)

Also, ive always wondered:

some people use:

Code:

---

int main(){
    return 0;
}

---

while others use

Code:

---

void main(){
 
}

---

Some people are right, while others are wrong.

void main(): FAQ

> #include <iostream.h>

#include <iostream>

Code:

---

#include <iostream>

using namespace std; //Note this

int main()
{
  cout << "Hey";
  return 0;
}

OK another Question... How to make a public variable so all functions/structures can access them?

>How to make a public variable so all functions/structures can access them?
After you've determined that you really do want this and understand that you have to live with the result, make a global variable:

Code:

---

#include <iostream>

int var; // Everyone can access me!

void foo()
{
  var++;
}

void bar()
{
  std::cout<< var <<endl;
}

int main()
{
  var = 10;
  foo();
  bar();
}
