Fat Percentage Calculator
Create an application that allows the user to enter the number of calories and fat grams in a food. The application should display the percentage of the calories that come from fat. If the calories from fat are less than 30% of the total calories of the food, it should also display a message indicating the food is low in fat. (Display the message in a label or a message box.) The application's form should appear similar to the one shown in Figure 4-35.
Figure 4-35 Fat Gram Calculator form
One gram of fat has 9 calories, so:
Calories from fat = fat grams * 9
The percentage of calories from fat can be calculated as:
Percentage of calories from fat - Calories from fat / total calories
Input validation: Make sure the number of calories and fat grams are numeric, and are not less than 0. Also, the number of calories from fat cannot be greater than the total number of calories. If that happens, display an error message indicating that either the calories or fat grams were incorrectly entered.
Use the following test data to determine if the application is calculating properly:

Cookie Calories A bag of cookies holds 40 cookies. The calorie information on the bag claims that there are 10 servings in the bag and that a serving equals 300 calories. Create an application that lets the user enter the number of cookies he or she actually ate and then reports the number of total calories consumed.
Tip, Tax, and Total Create an application that lets the user enter the food charge for a meal at a restaurant. When a button is clicked, the application should calculate and display the amount of a 15 percent tip, 7 percent sales tax, and the total of all three amounts.
Property Tax If you own real estate in a particular county, the property tax that you owe each year is calculated as 64 cents per $100 of the property’s value. For example, if the property’s value is $10,000, then the property tax is calculated as follows: Tax = $10,000 ÷ 100 × 0.64 Create an application that allows the user to enter a property’s value and displays the sales tax on that property.

- Account numbers sometimes contain a check digit that is the result of a mathematical calculation. The inclusion of the digit in an account number helps ascertain whether the number is a valid one. Write an application named CheckDigit that asks a user to enter a four-digit account number and determines whether it is a valid number. The number is valid if the fourth digit is the remainder when the number represented by the first three digits of the four-digit number is divided by 7. For example, 7770 is valid, because 0 is the remainder when 777 is divided by 7. The next problems rely on the generation of a random number. You can create a random number that is at least mi n but less than max using the following statements: Random ranNumberCenerator = new Random(); int randomNumber; randomNumber = ranNumberGenerator .Next(min, max);arrow_forwardFalling Distance When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period: d =1/2gt2 The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time in seconds that the object has been falling. Create an application that allows the user to enter the amount of time that an object has fallen and then displays the distance that the object fell. The application should have a method named FallingDistance. The FallingDistance method should accept an object’s falling time (in seconds) as an argument. The method should return the distance in meters that the object has fallen during that time interval.arrow_forwardTrue or False To close an application’s form in code, you use the statement Close.This();arrow_forward
- Software Sales A software company sells a package that retails for $99. Quantity discounts are given according to the following table: Quantity Discount 10–19 20% 20–49 30% 50–99 40% 100 or more 50% Create an application that lets the user enter the number of packages purchased. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount.arrow_forwardName Formatter Create an application that lets the user enter the following pieces of data: • The user’s first name • The user’s middle name • The user’s last name • The user’s preferred title (Mr., Mrs., Ms., Dr., etc.) Assume the user has entered the following data: • First name: Kelly • Middle name: Jane • Last name: Smith • Title: Ms. The application should have buttons that display the user’s name formatted in the following ways: Ms. Kelly Jane Smith Kelly Jane Smith Kelly Smith Smith, Kelly Jane, Ms. Smith, Kelly Jane Smith, Kellyarrow_forwardFat Percentage Calculator One gram of fat has 9 calories. If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food: Calories from fat = Fat grams × 9 If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat: Percentage of calories from fat = Calories from fat ÷ Total calories Create an application that allows the user to enter: • The total number of calories for a food item • The number of fat grams in that food item The application should calculate and display: • The number of calories from fat • The percentage of calories that come from fat Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.) Use the following test data…arrow_forward
- Latin Translator Look at the following list of Latin words and their meanings: Latin English sinister left dexter right medium center Create an application that translates the Latin words to English. The form should have three buttons, one for each Latin word.

The company charges $20.00 per hour for labor. Create an application that allows the user to enter the square feet of wall space to be painted and the price of the paint per gallon. The program should display the following data: • The number of gallons of paint required • The hours of labor required • The cost of the paint • The labor charges • The total cost of the paint jobarrow_forwardSales Tax and Total Create an application that allows the user to enter the amount of a purchase. The program should then calculate the state and county sales tax. Assume the state sales tax is 4 percent and the county sales tax is 2 percent. The program should display the amount of the purchase, the state sales tax, the county sales tax, the total sales tax, and the total of the sale (which is the sum of the amount of purchase plus the total sales tax).arrow_forward
- Distance ConverterIn the English measurement system, 1 yard equals 3 feet and 1 foot equals 12 inches. Use this information to create an application that lets the user convert distances to and from inches, feet, and yards. Programming Problems 263Figure 4-35shows an example of how the application’s form might appear. In the example, the user enters the distance to be converted into a TextBox. A ListBox allows the user to select the units being converted from, and another ListBox allows the user to select the units being converted to.arrow_forwardLike other controls, a control's property governs whether or not it appears on the form at runtime.arrow_forwardBook Club PointsSerendipity Booksellers has a book club that awards points to its customers based onthe number of books purchased each month. The points are awarded as follows:• If a customer purchases 0 books, he or she earns 0 points.• If a customer purchases 1 book, he or she earns 5 points.• If a customer purchases 2 books, he or she earns 15 points.• If a customer purchases 3 books, he or she earns 30 points.• If a customer purchases 4 or more books, he or she earns 60 points.Write a program that asks the user to enter the number of books that he or she haspurchased this month and then displays the number of points awarded.arrow_forward
