16th Week OJ Brush problem--problem e:b Constructors and destructors

Source: Internet
Author: User


When the class object is established, the system automatically completes the initialization of the object by the constructor of the class.
When the class object life cycle ends, the system automatically calls the destructor before releasing the object space.

This topic requires:
According to the main program (main function) and program execution results, combined with the constructor and destructor related knowledge, the following program section based on the completion of the entire design.

Tip: (1) You need to customize the plural class complex, and add the appropriate constructors and destructors to the class.
(2) The code that only submits the begin to end section


The real and imaginary parts of a complex number


Call the run results of the related constructors and destructors (which you need to analyze yourself), as shown in sample Output.

Sample Input
1.5 2.6
Sample Output
(1.5,2.6i) is constructed! (1.5,2.6i) is copy constructed!destructed!destructed!

Learning experience: This problem is the construction function and destructors, to master the definition of constructor overloading and the definition of destructors. Keep trying!!!
