SECTION B (60 Marks)
Attempt any four questions from this Section
Define a class called mobike with the following description;
Instance variables/data members:
int bno- to store the bike’s number
int phno – to store the phone number of the customer
String name – to store the name of the customer
int days – to store the number of days the bike is taken on rent
int charge – to calculate and store the rental charge
void input() – to input and store the details of the customer
void compute() – to compute the rental charge.
The rent for a mobile is charged on the following basis:
First five days Rs. 500 per day.
Next five days Rs. 400 per day.
Rest of the days Rs. 200 per day.
void displayi) – to diapay the details in the following format:
Bike No. Phone No. Name No. of days Charge [ 15]
Write a program to input and store the weight of ten people. Sort and display them in descending order using the selection sort technique. 
write a program to input a number and print whether the number is a special number or not. (A number is said to be a special number, if the sum of the factorial of the digits of the number is same as the original number).
Example: 145 is a special number, because 1 I+41+51= 1 +24+ 120= 145
(Where I stands for factorial of the number and the factorial value of a number is the product of all integers from 1 to that number, example 51=1’2’3’4’5=120). 
Write a program to accept a word and convert it into lowercase if it in uppercase, and display the new words by replacing only the vowels with the character following it.
Sample Input: computer
Sample Output: cpmpvtfr [ 15]
Design a class to overload a function compare() as follows:
(a) void compare(int, int)- to compare two integer values and print the greater of the two integers.
(b) void compare(char, char) – to compare the numeric value of two characters and print the character with higher numeric value.
(c) void compare(String, String ) – to compare the length of the two strings and print the longer of the two. [ 15]
write a menu driven program to perform the following: (Use switch – case statement)
(a) To print the series 0, 3, 8, 15, 24 ….. n terms (vlaue of ‘n’ is to be an input by the user.) [ 15]
(b) To find the sum of the series given below :
S = 1/2 + 3/4 + 5/6 + 7/8 …………….. 19/20.
