// Result of execution
//
// There are 3 wings.
// There are 12 feet.
// There are 4 eyes.
//
// There are 2 wings.
// There are 1000 feet.
// There are 2 eyes.

// There is no change in the result because int and float are
//  compatible types and the system will change from one to 
//  the other automatically.  Note the funny output of the
//  char type however.
