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 * 9. Make sure that the number of calories entered is not greater than fat grams * 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 * 9) / Calories

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

how to write this in pseudo code for both Module and function?

------------------------------

method:

-------

Module main ( )

/ / Local variables

double fatGramCalculator(double fatGrams, double calories)

// If fat grams or calories are less than 0, display a message and return -1

if (fatGrams < 0 || calories < 0)

Display ('Number of fat grams and calories must be greater than 0

return -1;

// If calories is greater than fat grams * 90, display a message and return -1

if (calories > (fatGrams * 9)

Display('Calories must not exceed fat grams x 9

return -1;

// Calculate percentage of calories from fat

double caloriesFromFat = (fatGrams * 9) / calories;

// Display calories from fat, multiplying percentage by 100 to remove decimal point

Display('%d percent of calories from fat,

caloriesFromFat * 100);

// If less than 30% of calories come from fat, display a message

if (caloriesFromFat < 0.3)

Display('Food is low in fat

// Return the number of calories from fat

return caloriesFromFat;

End Module

Function Real sum ( Real fatGrams, Real doubleCalories )

Declare Real result

Set result = ( fatGrams*9 ) / calories

Return result

End Function

is this right?
