Initialization of a Union Variable A union variable can be initialized, provided its storage class is either external or static. Only one member of a union can be assigned a value at any one time. The initialization value is assigned to the first member within the union.

Step by step
Solved in 3 steps
- Home Activity Your task is to create two classes namely data and calculation. The calculation class is a friend of the data class. The data class will be composed of two floating point data members namely a and b. The class will also be composed of a friend function display that can display all the data members. Course: CSCL-1208 Object Oriented Programming Techniques The calculation class is responsible for performing operations on the data class and hence it has three functions as follows: • A function to compute the Square of sums i.e. (a + b) =a²+ b² +2ab •A function to compute the Square of difference i.e. (a - b)² =a²+ b? -2abQuestion Object Oriented Programming c++ Write a program that defines a class with a data member to holds a "serial number" for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you'll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each about its serial number. They should respond I am object number 2, and so on.Language: C++ Subject: OOP Task:You have to write a program to store information of university students. There can be many students in university, so you can make a Student class and objects of class Student to store information. The university is interested in storing information about student’s name, enrollment, department, class, CGPA and gender. You can store this information as data member values for each object. But as you already know you cannot directly access data members of a class, so you need to make member functions to access data members. You can make as many member functions as you want. There are no restrictions. The University is interested in knowing the student’sname with highest CGPA in a specific class. For example if you entered information of 10 students from class BSIT 2 and information of 5 students from class BSIT 3, and it is asked to find name of student with highest CGPA in BSIT 2 then your program must be able to find details of highest CGPA student from…
- To make use of a virtual function in numerous ways, an application may utilise base class pointers or references to activate a virtual function.Programming language : c++ Question : Make a class Student with attributes StudentName, Enrollment, semester, section, course MarksObtained and Grade. Write appropriate constructors, get and set functions for data members. The data member grade is automatically calculated based on marks obtained out of 100 for each course.Computer Science A course and a teacher object have a many-to-one relation. You need to enable a function wherein a course cannot be saved without notifying the teacher. What should be done to accomplish the task?
- Among class data members, static members and non-static members are distinguished by the following characteristics: Provide an example of real-world application where you think a static data member would be useful.In order to use the same virtual function in a variety of forms and structures, a software application may need to execute a virtual function defined in a base class. A base-class reference or pointer is required.List situations when a copy constructor executes.
- functions return the value of a data member. A. Accessor OB. Member C. Mutator OD. Utilitywhen an application uses pointers or references from the base class to call a virtual function, allowing several implementations of the same functionality to use the same code.object oriented programing Design a class that has an array of floating-point numbers. The constructor should accept an integer argument and dynamically allocate the array to hold that many numbers. The destructor should free the memory held by the array. In addition, there should be member functions to perform the following operations: • Store a number at any index of the array • Retrieve a number from any index of the array • Return the highest value stored in the array • Return the lowest value stored in the array • Return the average of all the numbers stored in the array
