You are to write a basic fitness application, in C++, that allows the user of the application to manually edit diet and exercise plans. For this application you will need to create three classes: DietPlan, ExercisePlan, and FitnessAppWrapper.

Please provide an output and please make sure it works. I promise not to copy the code.

Diet Plan Attributes:

The class DietPlan is used to represent a daily diet plan. Your class must include three data members to represent your goal calories (an integer), plan name (a std::string), and date for which the plan is intended (a std::string). The maximum intake of calories for a day is stored in the goal calories.

Exercise Plan Attributes:

The class ExercisePlan is used to represent a daily exercise plan. Your class must include three data members to represent your goal steps (an integer), plan name (a std::string), and date for which the plan is intended (a std::string). Your goal steps represent the number of desired steps for a day.

Diet and Exercise Plan Operations:

Both the DietPlan and ExercisePlan should provide several member functions including: a constructor, copy constructor, and destructor. Remember that you will have to think about other appropriate member functions (think about setter and getter functions!). Member function editGoal () should prompt the user for a new goal, and use the value to change the goal in the plan. Each time a plan is changed, the plan must be displayed to the screen, using an overloaded stream insertion operator (see below).

In the same file in which each class declaration exists, three nonmember functions must be declared. Note: an overloaded operator is considered an overloaded function. The overloaded stream insertion (<<) for both displaying a plan to the screen and for writing a plan to a file, and the extraction (>>) operator for reading a plan from a file.

Observation: please notice that the DietPlan and ExercisePlan classes define very similar attributes and operations. In the future, we will be able to design around these similarities (using inheritance and polymorphism).

Fitness Application:

Each of the daily plans will be read from a file. Each file must consist of exactly seven daily plans, representing a full week of plans. The daily diet plans will be read from a file called dietPlans.txt and the daily exercise plans will be read from a file called exercisePlans.txt. The format of the files must be represented in the following way:

Plan name

Goal

Date in the form mm/dd/yyyy

(blank line)

Plan name

Goal

Date in the form mm/dd/yyyy

You must read in each of the daily plans by applying an overloaded stream extraction operator: fileStream >> DietPlan or fileStream >> ExercisePlan. The overloaded operator must be defined as a nonmember function to the DietPlan and ExercisePlan classes. Each plan is stored into the next available position in your linear data structure whether it be an array, vector, or linked list.

Observation: Inserting at the end of an array and vector requires (amortized) constant time. Inserting at the end of a linked list (with only a head pointer) requires linear time. Consider this idea as you develop your solution!

The class FitnessAppWrapper is used to wrap the application. This class should contain two lists (must be an array, vector, or linked list) of weekly (7 days) plans: one diet and one exercise weekly plan. It must also contain two fstream objects (input/output file streams): one for each file. It must define the following member functions (some prototypes are given to you, but not all!):

void runApp (void): starts the main application.

void loadDailyPlan (fstream& fileStream, DietPlan &plan): must define two of these functions; one for a DietPlan and one for an ExercisePlan. This function reads one record from the given stream. These will be considered overloaded functions! Precondition: file is already open!

void loadWeeklyPlan (fstream& fileStream, DietPlan weeklyPlan[ ]): must define two of these functions; one for a DietPlan and one for an ExercisePlan. This function must read in all seven daily plans from the given stream. Note: the array parameter would change if using a vector or linked list! This function should call loadDailyPlan () directly. Precondition: file is already open!

displayDailyPlan (): writes a daily plan to the screen. You must apply the overloaded stream insertion operator here! Note: you must determine the appropriate parameters and return type. Once again you must define two of these!

displayWeeklyPlan (): writes a weekly plan to the screen. This function must call displayDailyPlan (). Note: you must determine the appropriate parameters and return type. Once again you must define two of these!

storeDailyPlan (): writes a daily plan to a file. You must apply the overloaded stream insertion operator here! Note: you must determine the appropriate parameters and return type. Once again you must define two of these!

storeWeeklyPlan (): writes a weekly plan to a file. This function must call storeDailyPlan (). You must apply the overloaded stream insertion operator here! Note: you must determine the appropriate parameters and return type. Once again you must define two of these!

displayMenu (): displays nine menu options. These include:

Load weekly diet plan from file.

Load weekly exercise plan from file.

Store weekly diet plan to file.

Store weekly exercise plan to file.

Display weekly diet plan to screen.

Display weekly exercise plan to screen.

Edit daily diet plan.

Edit daily exercise plan.

Exit. // Note: this must write the most recent weekly plans to the corresponding files.

Other functions? There should be!

Observation: Many of the functions in the FitnessAppWrapper class are overloaded. Theres one version for use on a DietPlan and one version for use on an ExercisePlan. We know these functions are considered overloaded because they have the same name, but different parameter types. In the future, we could use templates, and let the compiler generate code for us, instead of implementing several versions of the same function ourselves.

BONUS:

Implement classes for ListNode and List to store the diet and exercise plans. You may need to implement a different linked list for each of the plans. In the future, this could be resolved by using templates.
