Transcription: This output statement prints the value of x after it has been inverted twice. Since the value of x is 1 over 3, the value of its inverse is 3 over 1. The inverse of 3 over 1 equals the original value of x, 1 over 3. Notice how calls to member functions whose return values are objects of a class can be concatenated elegantly in an expression. This feature is useful in many situations.
