14.12 LAB: Nutritional information (classes/constructors) Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "Water" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, amount of fat, carbs, and protein, and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for a food item. Ex: If the input is: Water the output is: Nutritional information per serving of Water: Fat: 0.00 g Carbohydrates: 0.00 g Protein: 0.00 g Number of calories for 1.00 serving (s): 0.00 Ex: If the input is: M&M's 10.0…
