What are the member variables?
Does this include a destructor? Why do you need a destructor in C++ but not in Java?
Member variables concept is in object-oriented programming. A member variable is a variable which is associated with a specific object and it can be accessible by all the methods in the object.
Destructor is used to delete the memory allotted to variables in C++.
But in Java, destructor is not required, since Java by default provides Garbage Collection which periodically frees the memory which is not being referenced for a specific period of time.

6. Declare an object Plane with nothing but a private constructor and destructor. You do not need to define either the constructor or destructor. 7. Create a vector that can hold Plane objects but do not set an initial size or initialize any elements 8. What kind of variable type is used to store a memory address 9. What operator is used to dereference a pointer to a structure? 10. If you intent on doing file I/O, what #include do...
Water default and overloaded constructor and destructor for a class Person with attributes name, age, height, weight. One of the constructors must initialize only the name. What is the purpose of the destructor? Explain with an example. Why do we need Private member Functions
Why are we required to provide a copy constructor and a destructor in C++ when they are not required in Java. Explain in detail.
C++ This exercise will introduce static member variables and static methods in class to you. Class Department contain information about universities departments: name students amount in addition it also stores information about overall amount of departments at the university: departments amount class Department { public: Department(string i_name, int i_num_students); ~Department(); int get_students(); string get_name(); static int get_total(); private: string name; int num_students; static int total_departments; }; Carefully read and modify the template. You have to implement private static variable "total...
How do i write a destructor for this class? #ifndef NODE_H #define NODE_H #include <iostream> using namespace std; class Node{ public: // Constructor // Preconditions: None // Postconditions: None Node(); // Destructor // Preconditions: None // Postconditions: Frees dynamically allocated memory ~Node(); // Overloaded Constructor // Preconditions: None // Postconditions: Initializes member variable with given argument Node(bool value); // ReplaceValue - Replaces m_value with opposite (if true then false or if false then true) // Preconditions: None // Postconditions: m_value...
In c++ What does operator overloading allow us to do ? Why must the << and the >> operators be overloaded as friend functions instead of member functions, for a user defined class ? What is the difference between an instance member variable and a static member variable ? How are call to static member functions made ? Describe the difference between reading a file using the >> operator and with the getline function What is inheritance What is a...

C++ Language Overview: Design an APP for a basketball team with a unique name. There should be at least 10 players. The member variables required include team member’s names, jersey number, position played, and at least 3 stats. Positions are small forward, power forward, center, shooting guard and point guard. 1. A.) Design a class with member variables and appropriate member functions Data should be stored in a read/write file consisting of team member’s names, jersey number, position played, and...
explain why member variables should be private with no access from outside class definition c++
