Object Oriented Programming & Computer Graphics Laboratory

GROUP A

· Constructor, Destructor:

1. Create a class named weather report that holds a daily weather report with data members day_of_month,hightemp,lowtemp,amount_rain and amount_snow. The constructor initializes the fields with default values: 99 for day_of_month, 999 for hightemp,-999 for low emp and 0 for amount_rain and amount_snow. Include a function that prompts the user and sets values for each field so that you can override the default values. Write a program that creates a monthly report.

Static member functions,friend class,this pointer,inline code and dynamic memory allocation :

2. Develop an object oriented program in C++ to create a database of the personnel information system containing the following information: Name,Date of Birth,Blood group,Height,Weight,Insurance Policy number,Contact address,telephone number,driving licence no. etc Construct the database with suitable member functions for initializing and destroying the data viz constructor,default constructor,copy constructor,destructor,static member functions,friend class,this pointer,inline code and dynamic memory allocation operators-new and delete.

· Operator overloading

3. Design a Class ‘Complex ‘ with data members for real and imaginary part. Provide default and parameterized constructors.Write a program to perform arithmetic operations of two complex numbers using operator overloading (using either member functions or friend functions).

4. Write a C++ program to perform String operations i. = Equality ii. == String Copy iii. + Concatenation iv. << To display a string v. >> To reverse a string vi. Function to determine whether a string is a palindrome To find occurrence of a sub-string. Use Operator Overloading

· Inheritance

5. Design a base class with name,date of birth,blood group and another base class consisting of the data members such as height and weight.Design one more base class consisting of the insurance policy number and contact address.The derived class contains the data members telephone numbers and driving licence number. Write a menu driven program to carry out the following things: i) Build a master table ii) Display iii) Insert a new entry iv) Delete entry v) Edit vi) Search for a record

· Templates

6. Write a program in C++ using function template to read two matrices of different data types such as integers and floating point values and perform simple arithmetic operations on these matrices separately and display it.

· Virtual functions & files

8. Create a class named Television that has data members to hold the model number and the screen size in inches,and the price.Member functions include overloaded insertion and extraction operators.If more than four digits are entered for the model,if the screen size is smaller than 12 or greater than 70 inches, or if the price is negative or over $5000 then throw an integer.Write a main() function that instantiates a television

object,allows user to enter data and displays the data members .If an exception is caught ,replace all the data member values with zero values.

GROUP B

1. Assignments to understand functions available in graphics library such as,

(a) Text and Graphics mode, initialization of graphics mode, graphics drivers,

switching between text and graphics mode, error handling.

(b) Color, Color Palette, Aspect ratio, Text: fonts, alignment, size, orientation

and justification.

(c) Graphics Primitives: Pixel, Line, Circle, Ellipse, Polygons, Line styles, Bar

graphs, Pie Charts, Histograms, filling a polygon, windowing.

(d) Writing a Graphics Editor

2. Write a program to implement algorithm for line and circle drawing.

3. Write a program to implement algorithm for filling a polygon using scan-fill

method.

4. Write a program to implement 2-D transformations.

5. Case study of any graphics tool.
