Class XII B- 2012-13
1.
C++
Write a program to play the following game:
The player guesses a number from 2 to 19 and then the program generates three random Revision
numbers from 101 to 119. If the sum of the digits of any of these numbers matches the
player’s number, then the player is declared as winner otherwise the player looses the game
2.
Write a program to generate a random number from 1 to 100 and let the user guess it in three C++
choices. In every choice, compare the number guessed by the user and give the hint as your Revision
number is very near to the expected number or your number is very far to the expected
number. If user guesses the random number within 3 choices, then declare as winner with % of
accuracy (correct guess in choice 1 is 100%, at choice 2 is 50%, at choice 3 is 30%)

Write a program to input a number and check whether it is a perfect number or not.
Example : 6 is a perfect number as sum of its factors 1 + 2 + 3 is again 6.
7.
Write a program to input a number and check whether it is a exact number or not.
Hint : if sum of factorials of each digit of a numbe is again the same number, then it is a exact
number.
Example : 145 = 1! + 4! + 5! (1+24+120 = 145)

16. Imagine a publishing company that markets both books and audio-cassete versions of its
works. Create a class publication that storea the title ( string) and price (float) of a publication.
From this class derive two classes : BOOK, which adds page count (int) and TAPE,which adds a
playing time in minutes (float). Each of these three classes should have a getdata() function to
get its data from the user at the keyboard, and a putdata() function to display its data.
Write main frunction to test the book and tape classes by creating objects of them and calling
all the funcitons.
17. Assume that the bank maintains two kinds of accounts for customers, one called as savings
account and the other as current account. The savings account provides compound interest
and withdrawal facilities but not cheque book facility. The current account provides cheque
book facility but no interest. Current account holders should also maintain minimum valance
and if the balance falls below this level, a service charge is imposed.
Create a class Account that storea customer name, account number and opening balance.
From this account class derive the classes Current and Savings to make them more spedific to
their requirements. Include necessary member funcitons. (Refer page 290 of 9th edition)
