Write a program to input the distance covered and calculate the amount paid by the passenger. The program displays the printed bill with the details given below:

Taxi No.                 :

Distance covered   :

Amount                 :

15) Using a switch case statement, write a menu-driven program to calculate the area of the following geometric shapes.

      i) area of circle ( area of circle = π*r2)

            ii) area of rectangle (area of rectangle = l*b)

      iii) area of square (area of Square = side * side)

16)      Write a Java program to print the Fibonacci series up to n terms where n is user input.

17)      Write a Java program to calculate the sum of digits of a number entered by the user.

18)      Write a Java program to check and display whether the entered number is an Armstrong number or not.

19)      Write a Java program to check and display whether the entered number is a Prime number or not.

20)      Write a Java program to check and display whether the entered 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 the same as the original number.)

For example 145 is special number, because 1! + 4! + 5! = 1 + 24 + 120 = 145

21)      Using the switch statement, write a menu-driven program :

(i) To check and display whether a number input by the user is a composite number or not.

(ii) To find the smallest digit of an integer that is input.

            For an incorrect choice, an appropriate message should be displayed.

22)      Write a Java program to print the sum of series 1 + (1+2) + (1+2+3)…….(1+2+3+…+n). The program should ask for the value of a number of terms n.

23)  Write a Java program to print the following pattern.
