uh...what error is this?

[SteveCRM]

This works fine in borland...but I get this in ms:

LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16
Debug/Guess My Number.exe : fatal error LNK1120: 1 unresolved externals

here is the code

#include <iostream.h>

int number;
int guess;
int dummy;

int main()
{
	//until i randomize NUMBER then its just going to be 34
   number=34;

	cout<<"Welcome To High Low!"<<endl;
   cout<<"===================="<<endl;
   cout<<"Enter a number between 1 and 100!"<<endl;
	cin>>guess;

   // if guess<number then it says too low, else it says too high, or if
   // you get it, it says congrats
	while (guess!=999)
	{
   	if(guess<number)
      {
       	cout<<"Too low!  Guess again."<<endl;
         cin>>guess;
      }
      else if(guess>number)
      {
       	cout<<"Too high! Guess again."<<endl;
         cin>>guess;
      }
      else if(guess==number)
      {
       	cout<<"Congratulations!  You Win!";
         guess = 999;
      }
	}
   //END OF WHILE STATEMENT

	cin >> dummy;
	return 0;
}

I know, Im a beginner...by the way, it would help me out a lot if you could also tell me how to make random numbers. But whats wrong?!?!?! Borland says its fine...
