Other than that the friend has privileged access to the private members of the class in which it is declared a friend, there are no implications. However, there has to a be a reason for the friend to require that access.

What are the limitations of friend function in c plus plus?
Only that they cannot be inherited by derived classes. This is "a good thing". Other than that, a friend function has full access to a class' private and protected members and you cannot limit its scope. At this data hiding feature of c++ is broken.
What is information hiding in software engineering?
The Modules should be designed specifically so that no information(Algorithm and data) contained within the module is not accessible to the other module that have no need of that information. Hiding implies that Effective modularity can be achieved by defining a set of independent modules that communicate with one another only through information necessary to achieve software function.
What is stegnography?
Stegnography is defined as the art of hiding information, data or messages in an image. Even the different file formats can be used for the purpose of hiding the information like for example the video or audio etc. The purpose is to pass on the information with out any regard or knowledge of others safely to the destination.

How does friend operator function differ from member operator function?
In C++, we know that private members cannot be accessed from the outside class.That is a non-member function cannot have an access to the private data of a class.However there could be a situation where we would like two classes to share a particular function.For example consider a case where two classes, manager and scientist have been defined.We would like to use a function income_ tax () to operate on the objects of both these classes.In such situation, C++ allows the common function to be made friendly with both the classes. Such a function needs not be member of any these classes.To make outside function friendly to a class, we have to simply declare this function as a friend of a class as shown below:Class ABC{………..Public:……..……..Friend void xyz (void); //declaration};When the function is logically coupled with the class (like your maze connectedness example)When the function needs to access private or protected members, it's better to make it a member than a friend. when it's a generic function that can be templatized to naturally work on other classes (look at the header for good example) .

What the difference between data hiding and abstraction?
Data hiding means, hiding some essential information or as you say a data from other end user or users and abstraction in simple language means hiding complex features and showing only essential features of any object. Was that information useful please let me know. In data hiding we hide the information by using access specifier private, public and protected..so it means we are hiding info from outside the world.But in abstrastion we express only essential feature.. Eg: Three set of customers are going to buy a bike First one wants information about the style. Second one wants about the milage. Third one wants the cost and brand of the bike.So the salesperson explains about the product which customer needs what. So he hiding some information and giving the revelant information.
