Explanation:
The advantages of java.util.Stack are as following:-
- java.util.Stack is an implementation of the vector class hence it can keep track of position of elements in the stack hence it is not required to store an additional pointer for each node.
- In the implementation it allocates space only that much is needed.
These are the two advantages of java.util.Stack.
Answer:
The solution code is written in Python 3:
- calories = int(input("Enter number of calories: "))
- fats = int(input("Enter number of fat in grams: "))
-
- if(calories > 0 and fats > 0):
- cf = fats * 9
- if(cf < calories):
- percent = cf / calories
- if(percent < 0.3):
- print("Food is low in fat")
- else:
- print("Error input. Calories from fat cannot more than total calories")
- else:
- print("Error input. Calories and fats must be more than 0")
Explanation:
Firstly, use input function to ask user to enter total number of calories and fat in grams (Line 1-2)
Next we do the first input validation to check if the calories and fats are more than 0 (Line 4). If so apply formula to calculate calories from fats. If not, print error input message (Line 5, 13)
Then we proceed to next input validation to check if calories from fact more than total calories. If so, proceed to calculate percentage of calories from fats and if it is lower than 30%, display the appropriate message (Line 6 - 9). If fail the second input validation, the program will display another error input message again (Line 11)
