Can we make class inside class in C++?

The inner class can access any non-static member that has been declared in the outer class . Scope of a nested class is limited by the scope of its (outer) enclosing class. If nothing is specified, the nested class is private (default). Any class can be inherited into another class in C# (including a nested class).

Nested Classes in C++ A nested class is a class which is declared in another enclosing class . A nested class is a member and as such has the same access rights as any other member. The members of an enclosing class have no special access to members of a nested class; the usual access rules shall be obeyed.4 Oca 2019

Nested classes are just like regular classes, but: they have additional access restriction (as all definitions inside a class definition do), they don’t pollute the given namespace, e.g. global namespace .31 Ara 2010

Nested Classes in C++ A nested class is a class that is declared in another class . The nested class is also a member variable of the enclosing class and has the same access rights as the other members. However, the member functions of the enclosing class have no special access to the members of a nested class.9 Eki 2018
