Either make the data members public, or make the member function a friend of the class containing the data member.
If you are asking about member functions. When we declare a function inside a class then that function becomes member function of that class and this function can access the whole class
Any member functions and data members declared as 'private' in a class, can only be accessed directly by functions within the class.They cannot be accessed directly by derived objects, nor from anywhere outside an object of the class, such as from the Main function.To access private class members, you must rely on what are called accessor functions. Accessor functions are functions inside the class, either public or protected, which automatically have access to private members.If a function from Main, or elsewhere outside the class hierarchy, needs access, then you need to use publicaccessor functions. For derived class access, you can use protected accessor functions.
Public, protected and private accessors only apply to code outside of the class. Instances of a class (objects) have complete and unrestricted access to all their own instance variables (data members). They also have unrestricted access to the instance members of all other instances of the same class whenever those instances are passed as arguments to a class member method. Static methods of the class have the same privilege, as do friends of the class. So the question isn't why an object can access its own public members without using an operator or member function. Any code outside of the class has that exact same right, but if an object has unrestricted access to its protected and private members, why should its public members be treated any differently?
Friend class is one which has been declared so (as a friend) inside other class to make it access the private members of the class which has extended it's friendship.For Example,class A{private:.......public:..............friend class B;};class B{.....................};As in the above code snippet, class A has extended it's friendship to class B by declaring B as it's friend inside it's area.Since the Class B has became a friend of A, B can directly access all the private members of A. But the reverse is not possible.Where as an abstract class is a one, which doesn't represent any particular object in nature. Instead they use give as abstract look of an object.For instance,When we say TATA Indca, Lancer, Ford Icon, Toyota Innova they are different car models. Each of them having their own properties and features, but all of them are Cars. So here, Car is an abstract class where as the others are concrete classes.
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) .
When a function is nested inside another function, the outer one is the parent, the inner is the child.

An IF Function can contain other functions as part of its condition, its True or it False parts. It can also contain another IF. When a function is inside another function, it is known as a Nested Function.

The keyword "friend" allows a function or variable to have access to a protected member inside a class.
No. Functions should be defined separately. So you would not define a function within a function. You can define one function, and while defining another function, you can call the first function from its code.
The short answer is that you can not, but there is a solution that will work for you. You are not able to automatically insert data into a cell from another cell; that would be a push of data, which Excel does not do. However, Excel can pull data from a cell.Put your formula in a cell. Use A1 for this example.Write another formula in the target cell to reference the value of A1. Use B1 for this example.In B1, put the formula, =A1 to show the value of A1 in B1.****this is not going to work for my prob dude.. check out discussion tab for more about my question, please. Please, please... please. :) need more help..

If one function is inside another, then the functions are nested.
That depends on the language. In the case of Java, just use the name of the field (data member), for example: myField In some other languages, a special keyword such as "this" must be used, for example: this.myField
=ROUND(AVERAGE(A1:A100),2) The answer you may be looking for is a nested function, as one is inside another. ROUND is a math function and AVERAGE is a statistical function.
