Write a program in C++ using classes that calculates area of triangle by allocating the memory dynamically to class objects

In programming, is it preferable to use unqualified references to subprograms, variables, and objects or fully qualified ones? Issues with C's primitive encapsulation and how they manifest in C++ are discussed.

Java Assignment: Experiment with naming rules in Java Does the language use static or dynamic scoping? Can scopes nest? Are they open or closed? Does the scope of a name encompass the entire block in which it is declared, or only the portion after the declaration? How does one declare mutually recursive types or subroutines? Can subroutines be passed as parameters, returned from functions, or stored in variables? If so, when are referencing environments bound? Justify your answers with suitable code snippet and its output.
