4 Marks

4.C. Differentiate between entry controlled and exit controlled loops with examples.

2 Marks

5a) Declare a structure book containing the following members: authorname, pages and price. Using book declare an array to store information about 3 books. Write a C++ program that will accept information for 3 books and display the same.    3 Marks

5b)Write a function to read elements into an array.

Write a function which takes as arguments the array name and size of the array and returns the average of all the elements of the array.

Use these two functions in the main appropriately to read and find the average.

Display the array elements and the average in the main program.    4 Marks

5d) List all the storage class of variables    1 Mark

6a) Create a class called car with member variables colour, cost, year_of_manufacture . Add member functions getdetails and display. getdetails is defined within the class, which takes all the information from the user. Another member function display is defined outside the class which displays all the information. Write a program to create an object of the class and invoke these functions in appropriate order.
