 // The following calls would be illegal


// cout << " The minimum value of the two values x and w is: " << min( x, w ) 
// 							             << endl << endl;


// However, the call can be made as follows: 
 cout << " The minimum value of the two values x and w is: " << min<double>( x, w ) 
							             << endl << endl;


 // or as follows, with a warning, as expected, which is conversion from 
 // 'double' to 'int', possible loss of data
 cout << " The minimum value of the two values x and w is: " << min<int>( x, w ) 
							             << endl << endl;
