Contact Hrs / week: 6                                         Total hrs: 96       

 

1. Write a C++ program to find the largest of three numbers using inline function.

 

2. Write a C++ program to sort an array of integer in ascending order using a function called exchange( ) which accepts two integer arguments by reference.

 

3. Write a C++ program to implement function overloading in order to compute power(m,n) where i) m is double and n is int ii) m and n are int.

 

4. Create a 'DISTANCE' class with :

-  feet and inches as data members

-  member function to input distance

-  member function to output distance

-  member function to add two distance objects

       Write a main function to create objects of DISTANCE class. Input two distances and output the sum.

 

5. Create a class called 'EMPLOYEE'  that has

-  EMPCODE and EMPNAME as data members

-  member function getdata( ) to input data

-  member function display( ) to output data

Write a main function to create EMP, an array of EMPLOYEE objects. Accept and display the details of at least 6 employees.

 

6. Create a class called 'TIME'  that has

-  three integer data members for hours, minutes and seconds

-  constructor to initialize the object to zero

-  constructor to initialize the object to some constant value

-  member function to add two TIME objects

-  member function to display time in HH:MM:SS format

            Write a main function to create two TIME objects, add them and display the result in HH:MM:SS format.

 

7. Create a class 'COMPLEX'  to hold a complex number. Write a friend function to add two complex numbers. Write a main function to add two COMPLEX objects.

 

8. Create a 'MATRIX' class of size m X n. Overload the ‘+’ operator to add two MATRIX objects. Write a main function to implement it.

 

9. Derive a class ‘MAT’ from MATRIX class created in program No. 8. Add a member function  to overload ‘*’ operator  to multiply two objects. (Single Inheritance)

 

10. Write a c++ program :

 a)   to illustrate multilevel inheritance.

 b)  to illustrate multiple  inheritance.

 

11. Create a 'STRING' class which overloads ‘ = = ' operator to compare two  STRING objects.

 

12. Write a C++ program to illustrate ‘this’ pointer and pointers to derived classes.

 

13. Create a base class called 'SHAPE' having

-       two data members of type double

-       member function get-data( ) to initialize base class data members

-       pure virtual member function display-area( ) to compute and display the area of the geometrical object.

Derive two specific classes 'TRIANGLE' and 'RECTANGLE' from the base class.  Using these three classes design a program that will accept dimension of a triangle / rectangle interactively and display the area.

 

14. Write a C++ program to read a list containing item name, item code and cost interactively and display the data in a tabular format as shown below:

 

NAME

CODE

COST

 

The Name and Code are left-justified and the Cost is right-justified with a precision of 2 digits. Trailing zeros are shown. Fill the unused spaces with Hyphen

 

15. Design your own manipulator to provide the following output specification for printing money value:

1) 10 columns width

2) The character '$' at the beginning

3) Showing '+' sign.

4) Two digits precision

5) Filling of unused spaces with ' * '

6) Trailing zeros shown

 

16. Write a C++ program that uses a single file for both reading and writing the data.

 

17. A file contains a list of names and telephone numbers in the following form:

Name              Tel. No.

 

Write a C++ program to read the file and output the list in the tabular format. The name should be left-justified and numbers right-justified. Use a class object to store each set of data.

 

18. Write an interactive, menu-driven program that will access the file created in program  No.17 and implement the following tasks:

i) To determine the telephone numbers of the specified person.

ii) To determine the name if a telephone number is given.

iii) To update the telephone number whenever there is a change.

 

19.  Write a C++ program that displays the size (in bytes) of a given file. The name of the file is specified as command line argument.

 

20. Define a function template for finding the minimum value contained in an array. Write main( ) function to find the minimum value of integer array and minimum value of floating point numbers in an array.

 

21.  Write a class template to represent a generic vector. Include member functions to perform the following tasks:

1) To create the vector.

2) To modify the value of a given element.

3) To multiply the vector by a scalar value.

4) To display the vector in the form (10, 20, 30,…..)

Note:  Execute programs in LINUX/Windows platform
