For example, some file formats are human readable but have slower performance (like a text file) whereas other file types will require a file reader (such as a LabVIEW data log) but have better performance. However, its very useful when the classes in your package implement a well-defined set of logic. It sets some restrictions on the class members not to get directly accessed by the outside functions. Because just the most necessary information is shown to the user, it helps to enhance the security of an application or software. That is, functions that take other functions as arguments, allowing for greater code reuse and abstraction. Benefits of encapsulation include: For the best encapsulation, object data should almost always be restricted to private or protected. Such method should be declared as private so that the user does not have access to it. The name mangling is created on an identifier by adding two leading underscores and one trailing underscore, like this _classname__dataMember, where classname is the current class, and data member is the private variable name. Encapsulation_Benefits EB_obj; A user can reuse its code once written and can save space and memory of code. It requires less maintenance and is more secured Question 3. OOP can be used to create applications such as web applications, mobile applications, desktop applications, and games. In the above example, the salary is a private variable. return y; Performing encapsulation is a great OOP practice, though its best when paired with a robust APM solution like Retrace for error monitoring. cout<
