Submit pseudocode for the following programming exercise:

Fat Gram Calculator

Design a program that asks for the number of fat grams and calories in a food item. Validate the input as follows:

- Make sure the number of fat grams and calories are not less than 0.

- According to nutritional formulas, the number of calories cannot exceed fat grams X 9. Make sure that the number of calories entered is not greater than fat grams x 9.

Once correct data has been entered, the program should calculate and display the percentage of calories that come from fat. Use the following formula:

Percentage of calories from fat = (fat grams x 9) / calories

Some nutritionists classify a food as low fat if less than 30 percent of its calories come from fat. If the results of this forumlas are less than 0.3, the program should display a message indicating the food is low in fat.

Here is the pseudocode for the Fat Gram Calculator program:

1. Prompt the user to enter the number of fat grams in the food item.
2. Read and store the value of fat grams in a variable called fatGrams.
3. Prompt the user to enter the number of calories in the food item.
4. Read and store the value of calories in a variable called calories.
5. Validate the input by checking if fatGrams and calories are not less than 0.
6. If either fatGrams or calories is less than 0, display an error message and terminate the program.
7. Otherwise, proceed with the calculations.
8. Check if calories is greater than fatGrams multiplied by 9.
9. If calories is greater than fatGrams multiplied by 9, display an error message indicating that the input is invalid.
10. Otherwise, calculate the percentage of calories from fat using the formula: percentageFromFat = (fatGrams * 9) / calories.
11. Check if percentageFromFat is less than 0.3.
12. If percentageFromFat is less than 0.3, display a message indicating that the food is low in fat.
13. Display the calculated percentage of calories from fat.
14. End the program.

Note: This pseudocode assumes the availability of basic input/output functions for reading user input and displaying output. The specific programming language and syntax can be used to implement this pseudocode.

I'll give you a headstart:

Input:
input fat_grams;
input calories;

Validate:
- Make sure the number of fat grams and calories are not less than 0.
- the number of calories cannot exceed fat grams X 9.

Calculations:
- Percentage of calories from fat = (fat grams x 9) / calories
- is it low-fat?

Output:
- Print input data
- print output information

my while loop will not work for this, it is, while fatGrams < 0 or calories < 0 or calories > fatGrams * 9

typically one would code like this:

do{
print: instructions;
enter fatGrams;
enter calories;
}while(data unsatisfactory);

So that it would request data at least once.

Do

Display Error: "Error: The number of calories and fat grams cannot be less than 0. The number of calories cannot be greater than fat grams * 9."
Display "Enter the correct number of calories."
Input calories
Display "Enter the correct number of fat grams."
Input fatGrams
While fatGrams > 0 and calories > 0 and calories < fatGrams * 9

the while part was just a while loop i originally did and it worked

it would also work with a do-while loop like what i typed above?

Basically, yes, it works.

From the user's point of view, it does not seem logical to see "Error,..." before he types in anything.

I would replace the "error" message with an insisting message, such as:

"Please enter non-negative values for ...., and ensure that ...< 9*..."

It would be nicer, of course, to insert a message indicating an error for the second time around, such as:

If (count greater than 1) Display "Sorry, there is an error in the input. Please follow the instructions carefully."

For this, you'll need a counter called count that was set to 1 before entering the loop, and incremented by 1 at the end of the loop.
