13076 - Dietary Guideline   

Status  |  Limits Submit

Description

Base on the dietary guideline from Ministry of Health and Welfare(衛福部) in Taiwan. We can divide food we eat into six categories: grains(全穀雜糧類), protein(蛋豆魚肉類), dairy(乳品類), vegetables(蔬菜類), fruits(水果類), fats and nuts(油脂與堅果種子類).

 

According to the figure below, we can know how many servings of each of these six foods should be consumed based on how many calories are consumed in a day.

To simplify, we only consider calories less than or equal to 1500 (considered as 1500 in the figure above), 1500 to 2000 (as 2000) and greater than 2000 (as 2500).

 

Your final goal is to print out a health report, based on what this person had for breakfast, lunch, and dinner. A health report based on a human who need to consume less than or equal to 1500 may look like this:

 

First,

 

  • the figure above shows how many servings of each of six kinds of food are included in this person’s breakfast (also lunch and dinner).

 

Second,

 

  • RDA is the short of Recommended Dietary Allowance based on the dietary guideline.
  • intake is the total servings of each of six kinds of food in the person’s daily meals (breakfast + lunch + dinner).
  • MAR is the short of Maximum Allowable Range, to simplify we always set to 0.5.
  • The status of one kind of food is based on the intake and RDA of this food. If the intake is in the range of RDA +/- MAR, the status should be “ok”; otherwise, should be “warning”.

 

Finally,

  • The health status is based on the total number of risks (how many “warning” you get). If total number of risks is less than or equal to 2, the status should be “Excellent”; if it is 3 or 4, the status should be “Average”; if it is larger or equal to 5, the status should be “Poor”.

 

/*******************************************************************\

 

You don’t need to handle the output format, and only need to implement seven functions below and correct the access method for classes Breakfast, Lunch, Dinner to be derived from class DietaryGuideline.

 

Thus, [Please read and understand the main.cpp first before you started to code]. Now let’s take a look of the functions you need to implement.

 

void DietaryGuideline::risksAnalysis(string *g_status, string *p_status, string *d_status, string *v_status, string *fr_status, string *fa_status, string *h_status) – Should change all the food_status with the rules mentioned above based on variable food (grains, protein, dairy…) and rda_food (rda_grains, rda_protein, rda_dairy…).

note: *g_status is for the string pointer of grains_status, *p_status is for pointer of protein_status (so as to *d_status, *v_status, *fr_status and *fa_status). *h_status is for the string pointer of health_status.

 

void Breakfast::eat(double g, double p, double d, double v, double fr, double fa) – should update the food variable in Breakfast and DietaryGuideline.

note: g represents how many servings of grains were consumed, p represents as protein, d represents as dairy, v represents as vegetables, fr represents as fruits, fa represents as fats and nuts.

 

void Lunch::eat(double g, double p, double d, double v, double fr, double fa) – Similar to Breakfast::eat().

 

void Dinner::eat(double g, double p, double d, double v, double fr, double fa) – Similar to Breakfast::eat().

 

void Human::eatBreakfast(double g, double p, double d, double v, double fr, double fa) – Should call Breakfast::eat().

note: g, p ,d, c, fr, fa represents how many servings of each kinds of food were consumed, respectively.

 

void Human::eatLunch(double g, double p, double d, double v, double fr, double fa) – Should call Lunch::eat().

 

void Human::eatDinner(double g, double p, double d, double v, double fr, double fa) – Should call Dinner::eat().
