My assignment asks me to Implement a Linked List class with FoodItem as the objects to be inserted in the class, and implement a PrintList function member that prints the name of each food item in the list. Implement a SelectPrint function member that only prints the food item names with a calorie count less than 300.
I'm stuck at the Linked List class, my professor wasn't very clear on how to do it, and I'm so confused. Here is my FoodItem code thus far, it's my Fooditem.h, fooditem.cpp, and main file.
FoodItem.h# include <iostream>
# include <string>
using namespace std;
#ifndef FOODITEM_H
#define FOODITEM_H
enum relationtype{LESS,EQUAL,GREATER};
class fooditem {
private:
string name;
char type;
double calories;
public:
fooditem();
fooditem(string,char, double);
void setname(string);
void settype(char);
void setcalories(double);
string getname();
char gettype();
double getcalories();
relationtype compareto(fooditem) const;
class notfound
{};// class not found
class negative
{}; // negative number
};
#endif
FoodItem.cpp#include <iostream>
#include <string>
using namespace std;
#include "fooditem.h"
fooditem::fooditem()
{
name = "water ";
type = 'v';
calories = 0;
}
fooditem::fooditem(string j, char k, double l)
{
name = j;
type = k;
calories = l;
}
string fooditem::getname()
{
return name;
}
char fooditem::gettype()
{
return type;
}
double fooditem::getcalories()
{
return calories;
}
void fooditem::setname(string j)
{
name=j;
}
void fooditem::settype(char k)
{
type=k;
}
void fooditem::setcalories(double l)
{
calories=l;
}
/*relationtype fooditem::compareto(fooditem w) const
{
if (calories==w.calories) return EQUAL;
if (calories < w.calories)return LESS;
if (calories > w.calories) return GREATER;
}
*/
