underined reference to main


Hi I keep getting the error

/usr/lib/gcc/i486-linux-gnu/4.3.2/../../../../lib/crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status

I have no idea where I went wrong in my coding. Any help would be appericated.
Thanks

Here is my code



#include <iostream>

using namespace std;



double Whereis( const float Px,
const float Py
)

{
if ( (540 < Px < 640) and (150 < Py < 210) )
{
return 0 ;
}

else ( (440 < Px < 500) and (290 < Py < 350) )
{
cout << "your in Stadium" <<endl;
}
}

Well, I've only done straight C, not C++, but I believe the main() fn is still required....

Ahhh...Ok...How about main?
Code:

#include <iostream>

using namespace std;



double Whereis( const float Px,
const float Py
)
{
if ( (540 < Px < 640) and (150 < Py < 210) )
{
return 0 ;
}

else ( (440 < Px < 500) and (290 < Py < 350) )
{
cout << "your in Stadium" <<endl;
}
}
main(){}
