Question

1. Write a list of book defining parameters. (5 at least)

o Name (String) – Topic (String) – Pages (int) – IsEnglishLanguage (bool) – Price

(float)

2. Declare and initialize the variables of book parameters.

3. Take input from user and output all the parameters given by user.

4. Create a function to initialize book parameter taken form user.

5. Initialize and store 2 books’ parameters. Print the book with more pages, total number of

pages.

7. Store the 3 books data using array (each parameter separate).

8. Use loop store 10 books data in array, given by user. Print the data after input using

function and loop.

9. Store one book data via pointer

10. Store one book data via Reference
