C++ Programming: A Practical Approach

162 C++ Programming

else

cout<< " Objects c1 and c2 are equal.";

The use of operator overloading improves the readability of the program.

4.2 Operator Overloading

Let us enhance Program 3.5 for the following requirement:

“Enhance a class CuboidMetal with a function checkEquality that can check whether the given

two objects of CuboidMetal class are exactly equal in dimension and returns true if both these

objects have same dimension, otherwise it should return false. Let us assume that c1 and c2 are

objects of CuboidMetal class. Then, c1.checkEquality(c2) should return a boolean value true if

these objects are exaclty matching; else, it should r ...
