What are benefits of encapsulation?

What are benefits of encapsulation? kindly tell me to the point.

•     Simplicity and clarity

As all data and functions are stored in the objects so there is no data or function around in program that is not part of any object and is this way it becomes very easy to understand the purpose of each data member and function in an object.

•     Low complexity

As data members and functions are hidden in objects and each object has a specific behavior so there is less complexity in code  there will be no such situations that a functions is using some other function and that functions is using some other function.

•    Better understanding

Everyone will be able to understand whole scenario by simple looking into object diagrams without any issue as each object has specific role and specific relation with other objects.
