Question

Q1(a) A class named “Employee” holds information like employee code, name,gender, year of joining. Write a program in C++ to create three objects of employee and enter some data into it through setters. Make getters and setters for all employee information. Then ask the user to enter current year. Display the names of those employees whose tenure is 2 or more than 2 years according to the given current year only using getters

(b)A class named “Employee” holds information like employee code, name,gender, year of joining. Write a program to create five hundred objects (Array of employee objects )of employee and enter some data into it through setters. Make getters and setters for all employee information. Then ask the user to enter current year. Display the names of those employees whose tenure is 5 or more than 5 years according to the given current year only using getters.
Note: employee code is automatically assigned to newly created object by calling default constructor

(b) Define a class StudentReport with the following specification:
Private members :
adno 4 digit admission number
name 20 characters
marks an array of 5 floating point values
average average marks obtained
GETAVG() a function to compute the average obtained in five subject
Public members:
READINFO() function to accept values for adno, name, marks. Invoke the function   
GETAVG()

DISPLAYINFO() function to display all data members of StudentReport on the screen.
You should give function definitions outside the class using scope resolution operator.
