You work in a printing office that the machine there can print documents in different colors. It gets an integer number between 1 to 7 and prints the documents in rainbow colors, as shown in the following table:

Number Matched Color

1 Violet

2 Indigo

3 Blue

4 Green

5 Yellow

6 Orange

7 Red

Design an algorithm and write a C++ program to do the following:

• Prompt user to enter a number between 1 and 7
• Use selection structure such as if-else or switch to find the color based on the previous table
• Output the color related to input number. See the sample output.
• Save the output in a file named “color.txt”.

Sample Run

Enter a number between 1 and 7: 2

You have selected number 2 which is orange.

Output File "color.txt"

You have selected number 2 which is orange.

Here are the numbers and match colors:

1 ------- Violet

2 ------- Indigo

3 ------- Blue

4 ------- Green

5 ------- Yellow

6 ------- Orange

7 ------- Red

Write a Program: Invoice 

A customer makes a purchase at the store. The tax rate is 8% on all purchases 

except groceries. The store offers a 5% discount to seniors 60 and over. You 

should ask the user three questions: what they have bought (use a menu 

displaying bread, milk, or soap), what the purchase price is, and how old they are. 

Your goal is to print a formatted invoice with the following line items: price, tax, 

discount, and total. The discount should only be printed if applicable.  

You should test your program with 5 data sets: with and without tax and with and 

without the senior discount. The fifth data set makes an invalid choice of the 

menu item, in which case your program should not ask any more questions and 

output an error message.

WEB230 JavaScript 1 Assignment 3 - Quiz Average In this assignment we will write a JavaScript program to calculate the average of a set of quiz marks. Instructions 1. Create variable containing an array that will contain five or more numbers that represent the marks on quizzes. It is assumed that all quizzes will be out of 10 so the numbers must be values between 0-10. 2. Create a function that will take the array as an argument and return the average of the quizzes. 3. Output a text message with the values of the quizzes, space seperated without brackets. Use a template literal when constructing the output strings (AKA back-ticks, template literals are explained in the section on Strings in Chapter 1). 4. Output a text message with the final average rounded to one decimal place. Again use a teplate literal. 

You are hired by an ice-skating center. Your job is to write a program to do calculate the admission fees as follows: 

• Children 6 and younger $8.50

• Children 7 and older. $10.50

• Adults $12.00

• Seniors $9.50

There will be 10% tax. PNG students, staff, and faculty will receive 25% discount (before tax).

Design an algorithm and write a C++ program that prompts the user to input the number of tickets in each group age and if the user is a student, staff, or faculty at PNG. The program calculates and outputs the admission fees as illustrated in the sample runs.

Output:

Are you PNG student, staff, or faculty?

Enter Y for yes or enter N for no: Y

Enter the number of children 6 and younger : 1

Enter the number of children 7 and older : 1

Enter the number of adults : 1

Enter the number of seniors : 1

  ******You received %25 Discount*****

Subtotal ......$30.38

Tax ...........$3.04

Total .........$33.41
