Ok so here is my code:

# include <iostream>

using namespace std;
int main()
{
const float fahrenheit = 72.0;
const float celsius = (5.0 / 9.0) * (fahrenheit - 32.0);

cout << celsius << endl;

return (0);
}

When I click build and go I get this error:
command/developer/usr/bin/g++-4.0 failed with exit code 1 duplicate symbol_main in


Any help will be appreciated

I have forwarded this to Jon and he will reply soon....welcome to the boards.
