6 FROM THE CONCEPTS OF OOPS 1) Write a program in C++ to download + = operator to add 2 distances given in feet and inches. (10 Marks) 2) An educational institution wishes to maintain a database of its employees. The database is divided into a number of classes, as shown below. Specify all the classes and define functions to create a database and retrieve individual information as and when required. Assume necessary data. (10 Marks) Staff Code name Teacher Officer Subject Typist Grade experience Speed dept. experience Regular Basic sal. Casual Duration 3) Using constructor write a program in C++ to generate first n terms of Fibonacci Series. Fibonacci Series is 0,1. 1,2,3,5,8.. (10 Marks) Page 6

7 4) Create a class Float that contains one Float data member, overloaded all the four arithmetic operators so that they operate on the objects of FLOAT. 5) Create a base class Rectangle that contains Length and Width as data members. From this class drive a class named Box that has additional data members named depth. The function members of base Rectangle class should consist of a constructor and an area () function. The derived Box class should have a constructor and an override function named area () that returns the surface area of Box and a Volume function. Write a C++ program on above class calling all the member functions. (10 Marks) 6) Write a class to represent a vector (a series of float values) include member functions to perform the following task: i) To create the vector ii) To modify the value of a given element iii) To multiply by a scalar value iv) To display the vector in the form (10,20,30 ) (10 Marks) 7) Create a base class called shape. Use this class to store two double type values that could be used to compute the area of figures. Derive two specific classes called triangle and rectangle from the base shape. Add to the base class, a member function get_data () to initialize base class data members and another member function display_area () to compute and display the area of figures. Make display_area () as a virtual function and redefine this function in the derived classes to suit their requirements. Using these 3 classes, design a program that will accept dimensions of a rectangle and display the area. Remember the two values given as input will be trated as lengths of two sides in the case of rectangles, and as base and height in the case of triangles, and used as follows: Area of rectangle = x*y Area of triangle = (1/2)*x*y (9 Marks) 8) Write programs to evaluate different functions to % accuracy: 1) sin x = x- (x3/3!)+(x5/5!)-(x7/7!)+.. 2) cos x = 1-(x2/2!)+(x4/4!)-(x6/6!)+ (5 Marks) Page 7

8 9) An educational institution wishes to maintain a database of its students. The database is divided into number of classes, whose relationships are shown below. Fig. below also shows the minimum information required for each class. Specify all the classes and define functions to create the database and retrieve individual information as and when required. (12 Marks) Student Roll no. Sports Score Test Mark 1 Mark 2 Results Score 10) Develop a class for linked list (Dynamic data structure) with the following member functions to carryout the following: (20 Marks) (i) Create a linked list of store set of integer data. (ii) Display the Linked list. (iii) Insert a node containing data in a sorted list (iv) Delete a node from the list containing a specific data. Use object as node rather than using a struct variable to model a node. Page 8
