The above example is nearly identical to the first example, except that the class variables are now private.

Since the variables are now private, we cannot access them directly from main(). Hence, using the following code would be invalid:

// invalid code
obj.length = 42.5;
obj.breadth = 30.8;
obj.height = 19.2;
Instead, we use the public function initData() to initialize the private variables via the function parameters double len, double brth, and double hgt.
