This constructor takes one argument, also called one argument constructor. The main use of copy constructor is to initialize the objects while in creation, also used to copy an object. The copy constructor allow

For information on how objects are destroyed, seeHandle Class Destructor. Output Object Suppressed You can suppress the assignment of the class instance to theansvariable when no output variable is assigned in a call to the constructor. This technique is useful for apps that creates graphical inter...
9.1.1 Constructor and Destructor Many classes need some initialization when they are created. Any class that creates a resource in the constructor will probably need a destructor to release the resource when the class is destroyed. The resource could be an I/O channel, memory resources or other...

Class Designersupports anonymous classes.Anonymous class typesare classes declared without an identifier. They cannot have a constructor or destructor, cannot be passed as arguments to functions, and cannot be returned as return values from functions. You can use an anonymous class to replace a class...
These cannot be used together and both should be first on the function declaration line.Because the class name is specified on the command line, when used for a constructor or destructor, the class name is specified in the input file using the character '@'. Here are some examples that ...
