public class date
{
private int day; // from 1 to 31
private int month; // from 1 to 12
private int year; // from 2000 upwards
public void advance (); // move to next day
};
Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000.
Implement setters for day, month, and year.
Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.

The constructor should initialize the name (a string) to "None" 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, 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 both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…arrow_forward
