- Create an Organization class. Organization has 10 Employees (Hint: You will need an array of pointers to Employee class) Organization can calculate the total amount to be paid to all employees Organization can print the details(name & salary) of all employees note: write code in main,header and function.cpp fileWhen using pointers or references to a base class, how should software invoke the same virtual function in different forms and structures?Structures, like any other type, may have their own set of pointers. Structures that nest Returning Structure from a Function Structures' pointers Structure of the data
- Class and Data members: Create a class called Student that stores a student’s grades (integers) in a vector (do not use an array). The class should have data members that store a student’s name and course for which the grades are earned. Constructor(s): The class should have a 2-argument constructor that receives the student’s name and course as parameters and sets the appropriate data members to these values. Member Functions: The class should have functions as follows: Member functions to set and get the student’s name and course variables. A member function that adds a single grade to the vector. Only positive grades are allowed. Call this function AddGrade. A member function to sort the vector in ascending order. A member function to compute the average (x̄) of the grades in the vector. The formula for calculating an average is x̄ = ∑xi / n where xi is the value of each grade and n is the total number of grades in the vector. A member function to determine the lowest…When using base class pointers or references, how should a program call the same virtual function in different forms and structures?Class and Data members: Create a class called Temperature that stores temperature readings (integers) in a vector (do not use an array). The class should have data members that store the month name and year of when the temperature readings were collected. Constructor(s): The class should have a 2-argument constructor that receives the month name and year as parameters and sets the appropriate data members to these values. Member Functions: The class should have functions as follows: Member functions to set and get the month and year variables. A member function that adds a single temperature to the vector. Both negative and positive temperatures are allowed. Call this function AddTemperature. A member function to sort the vector in ascending order. Feel free to use the sort function that is available in the algorithm library for sorting vectors. Or, if you would prefer to write your own sort code, you may find this site to be helpful:…
