Practical Assignment 3

Subject- OBJECT ORIENTED PROGRAMMING WITH C++

1. Write a class with data members name, age, weight. Use constructors and destructors for the class.
2. Use a friend function to find average of a given number.
3. Use a copy constructor and print the value of an object four times.

4.      Write a program that substitutes an overloaded += operator. This operator should allow statements like c1+=c2, where c2 is added to c1 and the result should be left in c1, display the output.

5. Define a class string that contains character pointer and the length of the string as data members. Overload + operator to concatenate the two strings.
6. Define a class string that contains character pointer and the length of the string as data members. Overload + operator to concatenate the two strings.
7. Create as class student which stores the roll number, name; class test that stores marks obtained in two subjects; class result which contains the total marks obtained in the test. The class result can inherit the details of marks obtained in the test and the roll_no of the student class. Write a main function to implement the above class and display the output.
8. Write a c++ program that demonstrates class to basic and basic to class conversion
9. Write a program that defines a generic base class called fruit that describes certain characteristics of fruit. This class is inherited by two derived classes called Apple and Orange. These classes supply specific information to fruit that are related to these types of fruit.
10. Write a program to accept integer and float values from the user. Write the values in the file and print it on the screen.
11. Write a program that reads a text file and creates another file that is identical except that every sequence of consecutive blank spaces is replaced by a single space.
12. Write a program which reads a text from the keyboard and displays the following information on the screen in two columns

1) Number of lines.

2) Number of words.

3) Number of characters.
