There are three tickets for a concert. The VIP tickets cost $120, premium tickets cost $80, and regular tickets cost $40. Prompt the user how many tickets of each category he would like. Then print an invoice with overview of the order and total price. Include a sales tax of 9.25%. 

 

How many tickets would you like to order? VIP Tickets ($120): 0

Premium Tickets ($80): 4

Regular Tickets ($40): 2

 Invoice:

VIP:        $120 x 0 = $  0.00

Premium:  $ 80 X 4 = $320.00

Regular:  $ 40 x 2 = $ 80.00

Sales Tax:    9.25% = $ 37.00 ------------------------------ Total Price:       $437.00  

                  

Problem 3                              Program a Calculator                                                      
Write a program that can be used as a calculator. Prompt the user to enter which operation he/she would like to perform, that is addition, subtraction, multiplication, or division. Use a switch statements to properly handle the operator entered by the user. Then prompt the user to enter two operands. An example of the program may look like this:

 

Calculator

-------------------

What operation would you like to perform?

Addition (+), Subtraction (-), Multiplication (*), or Division (/)

Enter an operator: +

Enter operand 1: 23  

Enter operand 2: 45

The results is: 23 + 45 = 78

 

Problem 4                              Months                                                                               
 

Write a program that determines the season based on the month. The program prompts a user to enter a month (1-12) and then prints if that month is in spring, summer fall or winter. The program must also check if a valid month was entered. For simplicity, assume: 1-3: spring, 4-6: summer, 7-9 fall, 10-12 winter.

 

Enter a month (1-12): -5                  Enter a month (1-12): 7 That is not a valid month!               The 7. month is in fall!

 

OR                                                                              OR 

 

Enter a month (1-12): 3                   Enter a month (1-12): 14

The 3. month is in spring!                  That month must be in the future.
