In C++, if a member of a class is private, we cannot access it outside the class, but what if the member variable is protected?
Step by step
Solved in 2 steps
- C++ True/False: a member function in a class can access all of its class's member variables, but not if the variables are private.We don't use object to access the static member function of the class in C++ i.e. it can also be invoked without the help of the object. Why?C++ Friend function concepts Do not use operator overloading Create a class User with private member variables "id". In the class define a function increment_user_id() which will increment the id and return it as well. Create another method "void show_Id()" to show the id for a particular object. Create a constructor of User class where increment the Id by calling the increment_user_id() method for every new object . Finally create two objects of the class and print their corresponding id's on console.
- True or false: Like any C++ function, a constructor may be overloaded, providing each constructor has a unique parameter list.What are the three things that you are required to perform for classes that include member variables that are pointers?In a header file the defined static member variables go outside of the class declaration. is it True or False ??
- What is the object member access operator for?TRUE OR FALSE: In C++, comments that begin with the "multi-line" comment symbol can't be nested. A member function of a class has access to only the public data members of the class. If a C++ function does not take any parameters, parenthesis around the empty parameter list are still required. The size of a pointer variable depends on the type that it is pointing to.Employee Class (Medium) Write a class in C++ named Employee that has the following member variables: name. A string that holds the employee’s name. idNumber. An int variable that holds the employee’s ID number. department. A string that holds the name of the department where the employee works. position. A string that holds the employee’s job title. The class should have the following constructors: A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position. A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string (""). A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable. Write appropriate mutator functions…
- In C++, a function contained within a class is called (A) a method (B) a class function (C) member function (D) none of theseObject oriented programming C++ Use Classes Write a C++ program in which each flight is required to have a date of departure, a time of departure, a date of arrival and a time of arrival. Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…There is access to private members of a class by any function defined outside the class. true or false c++
