A company wants to transmit data over the telephone, but is concerned that its phones could be tapped. All of the data are transmitted as two-digit integers. The company has asked you to write a program that encrypts the data so that it can be transmitted more securely. Your program should read a two-digit integer and encrypt it as follows: Replace each digit by (the digit plus 7) modulus 10). Then, swap the first digit with the second and print out the encrypted integer

3. Write a program that computes the area of a circular region (the shaded area in the diagram) given the radius of the inner and the outer circles, ri and ro, respectively.










We compute the area of the circular region by subtracting the area of the inner circle from the area of the outer circle.

5. Write a program that displays the recommended weight in kilograms, given the user’s age and height in centimeters. The formula for calculating the recommended weight is

Recommended = (height – 100 + age %10) *0.90

Write a program that computes the total ticket sales of a concert . there are three types of seating’s : A, B, and C. the program accepts the number of tickets sold and the price of a ticket for each of the three types of seats. The total sales are computed as

totalSales = numberofA_Seats * priceperA_Seat +

numberofB_Seats * priceperB_Seat +

numberofC_Seats * priceperC_Seat ;

Write this program, using only one class, the main class of the program.
