C++ Programming: A Practical Approach

You can modify Program 3.15 with the aforementioned implementation of a copy constructor

and execute the program. Another use of this pointer is that when name of parameters passed

the parameters passed to the CuboidMetal constructor as shown in the following code are

same as the attributes of CuboidMetal class which is is differentiated by using this pointer as

follows:

CuboidMetal(char* metalType,float length,float breadth,float height, ...
