"Defining OO as based on the use of class hierarchies and virtual functions is also practical in that it provides some guidance as to where OO is likely to be successful"

This quote by Bjarne Stroustrup suggests that defining Object-Oriented (OO) shows as based upon the use of class hierarchies and virtual functions is a practical method. By doing so, it supplies assistance regarding where OO programming is likely to be effective. Class hierarchies are a way of arranging classes into a tree-like structure, with each class having a moms and dad class and potentially numerous kid classes. Virtual functions are functions that can be bypassed by child classes, enabling more versatility and personalization. By utilizing these 2 principles, OO programs can be more effective in particular situations. For instance, when handling intricate data structures, class hierarchies can assist organize the data and virtual functions can help personalize the habits of the information. By supplying assistance regarding where OO programs is most likely to be successful, this definition of OO shows can assist designers make much better choices when designing their applications.
