sol: Benefits of an object-oriented approach when developing a system pare as follows % It provides the feature o encapsulation le, it binds data. and methods together and thus keeps safe from outside, Only data of ano a class can be las accessed by the member functions * Whenever any applicattan is developed, first problem is defthed, analysed and it would be easter to understand complete workflow of problem if OOP approach is followed x It's easy to reuse. # suppose an application is developed and suddenly a requirement arises to add some features in that application, if that application is developed using object ostented approach then it would be easy to update and maintain " s provide better control and performance se provides better seasity. It reduces the development time and cost & It improves the quality of the system due to program reuse It provieces better security as data is bound with an object whereas in procedural approach data moves from one function to another and it can be accessed from anywhere. wokerega
