Create a C# program 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.

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 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:

Calories and Fat Percentage Fat

$200$ calories, $8$ fat grams Percentage of calories from fat: $36\%150$ calories $2$ fat grams Percentage of calories from fat: $12\%($a low$-$fat food$)$

$500$ lories, $30$ fat grams Percentage of calories from fat: $54\%$

I know my math is off the test didn't show $36\%$ it gave me an insane number instead $-$ I also need a checkbox tp put in whether the food item is a high or low food item
