What else can I help you with?
What are nested structures?
Nested structures means we can have a structure inside another eg: struct A { ........... ............ struct B { ........ ........ }b; }a;
What is nested class and what is its use in c plus plus?
A nested structure is simply one structure inside another. The inner structure is local to the enclosing structure. struct A { struct B {}; }; Here, we can instantiate an instance of A as normal. A a; But to instantiate B we must qualify the type because it is local to A: A::B b; If B were only required by A, then we can prevent users from instantiating instances of B simply by declaring it private: struct A { private: struct B {}; };
What is the difference between n-- and --n in C plus plus statement?
If these expressions are stand-alone (not nested), then they do the same thing, ie increment 'n'.
Can include files be nested in c?
Yes, include files can be nested in C and C++. In fact, most library implementations do just that.
Can you use c in c plus plus without using class and object?
Sure.

Can a c plus plus class be derived from a Java class?
No.

What do you understand by a Nested Class?
A nested class is a class that is declared within the scope of another class, the enclosing or outer class. class A // enclosing class { public: class B {}; // nested class }; Note that although class B is declared public in this example, keep in mind that it is still scoped to class A. Therefore the following code will fail to compile: int main() { B b; // Compiler error! } Instead, you must use scope resolution: int main() { A::B b; // OK } If class B were declared private to class A, then only class A and friends of class A have access to class A::B. If declared protected, accessibility extends to derivatives of class A. Nested classes may also inherit from other nested classes within the same enclosing class. class A { class B {}; class C : public class B {}; }; Keep in mind that nested classes are scoped to the enclosing class and are primarily used to reduce the visibility of the nested class, particularly when combined with private or protected access. When you have a class that is only of relevance to the enclosing class, this makes perfect sense. However, if the nested class is declared public, you have the option of using an embedded object or a nested class. But the point of scope resolution is in order to reduce the chances of programmer errors, particularly when using two or more classes with the same name but with different implementations.
What is nested class?
A class declared as a member of another class is called as a nested class or a class with in class. the general syntax of the nested class is: class outer_class_name{ private: //data protected: //data public: //methods class inner_class_name{ private: //data of inner class public: //methods of inner class };//end of inner class };//end of outer class
What is the role of object in c plus plus?
An object in C++ is an instance of a C++ class.
What is the difference between n-- and --n in C plus plus statement?
If these expressions are stand-alone (not nested), then they do the same thing, ie increment 'n'.

How do you do nested strcutres program in c plus plus?
As its name suggests, a nested structure is a structure which contains another within it. Here is an example in which the "nApple" structure is nested withing the "nTree" structure: #includestruct nApple{int stem;int skin;};struct nTree{int leaves;nApple redDelicious;nApple grannySmith;};
What is the unit of programming in c plus plus A. Function B. class C. object D. Attribute?
B. Class.
What is the difference between local class and nested class?
The main difference between a local class and a nested class is, local class can be used for once of a perticular part where as nested class can be used used anywhere through out the program.

Write down the various features of Nested class?
A nested class is a class defined within another class, and it can be categorized into static and non-static (inner) nested classes. Features of nested classes include encapsulation, as they can access the enclosing class's members, including private ones. They also help in logically grouping classes that are only used in one place, enhancing code readability and maintainability. Additionally, static nested classes do not require an instance of the enclosing class, while inner classes do.
