Did you intend for the line:
cout<<end;

to really be:
cout<<endl;

I did a quick check using MS VS2005. The following compiles correctly. Changing the line:
cout<<endl;

to:
cout<<end;
gives a compile error
--------------------------------
Below compiles using VS2005
--------------------------------

#include <tchar.h>
#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
cout << "-Calculate the area of a circle-" << endl;
cout << endl;
cout << "Radius = " << 10 << endl;
cout << "Area = " << (3.14*10*10) << endl;

return 0;
}

missed the end
-------------------------

#include <tchar.h>
#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
cout << "-Calculate the area of a circle-" << endl;
cout << endl;
cout << "Radius = " << 10 << endl;
cout << "Area = " << (3.14*10*10) << endl;

return 0;
}

I guess the double blank lines caused the posting applet to clip the last two lines. Here they are finally, I hope.
--------------------
return 0;
}

Nope, for some reason the last lines which are not posting.
Anyway, the last lines are the same as your source.
