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 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. 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 Fat Percentage Calculater Entor the number of colonos in the food 200 Enter the number of lat grams in the food Parcentage of cainnes that come from tar 300 % Calculate 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: Percentage Fat Percentage of calories from fat: 36% Percentage of calories from fat: 12% (a low-fat food) Calories and Fat Clear 200 calories, 8 fat grams 150 calories, 2 fat grams

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
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.
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
Fat Percentage Calculater
Entor the number of colonos in the food 200
Enter the number of lat grams in the food
Parcentage of cainnes that come from tar 300 %

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:
Percentage Fat
Percentage of calories from fat: 36%
Percentage of calories from fat: 12% (a low-fat food)
Calories and Fat
