C++ program, inventory.cpp implementation
Mostly need the int load(istream&) function.
int load(istream & s){
std::string line = "";
std::string word = "";
int count = 0;
while(s){
s.getline(line);
stringstream ss(line);
Item *i = new Item();
ss>>word;
int id = std::stoi(word);
i->setId(id);
word = "";
ss>>word;
i->setName(word);
word = "";
ss>>word;
double price =
std::stod(word);
i->setPrice(price);
word = "";
ss>>word;
int q = std::stoi(word);
i->setQuantity(q);
line = "";
if(!addNewItem(i)){
//if duplicate id present add its quantity.
stockIn(i->getID(),i->getQuantity());
}
count++;
}
return count;
}

C++ program, item.cpp implementation. Implementation: You are supposed to write three classes, called Item, Node and Inventory respectively Item is a plain data class with item id, name, price and quantity information accompanied by getters and setters Node is a plain linked list node class with Item pointer and next pointer (with getters/setters) Inventory is an inventory database class that provides basic linked list operations, delete load from file / formatted print functionalities. The majority of implementation will be done...
Objectives Familiarize the student with: implementing data structures in C++; dynamic allocation of C++ objects. Scenario There are some classic data structures in computer science. One example of this that you've seen in the lectures is called the stack. In the next few exercises, we'll build yet another classic data structure, the linked list. To be exact, we'll be building the singly linked list. The building block of a singly linked list is a node, which consists of two parts:...
This is a c++ class utilizing class templates and linked lists and Nodes. I need to implement the following member function(s) to LinkedBag.cpp. Node.hpp/cpp should be fine but if you feel like there needs to be a change for compilation or testing, feel free to do so but make sure to comment on why it was done. In this case, I need to join the original items with the user items(a_bag). So if the original has {1,2,3} and a_bag has...
C++ Create a class that implements a sorted, doubly-linked list: Start with a copy of the sortedList class. Call your new class doublyLinkedList. Convert the baseline code into a doubly linkedlist, and thoroughly test all existing operations (make sure to check all edge conditions), and then implement the new operations below. The class should have the following additional class methods: • A reverse method: this method will reverse the order of the doubly linked list. This method takes no parameters,...
Double linked list implementation of PutItem function. How to fix my code to get desired output below: Output: 2 5 8 #ifndef ITEMTYPE_H #define ITEMTYPE_H enum RelationType { LESS, GREATER, EQUAL}; class ItemType { public: ItemType(); void setValue(int newValue); int getValue() const; RelationType ComparedTo(ItemType newItem); private: int value; }; #endif // ITEMTYPE_H // ItemType.cpp #include "ItemType.h" ItemType::ItemType() { value = 0; } void ItemType::setValue(int newValue) { value = newValue; } int ItemType::getValue() const { return value; } RelationType ItemType::ComparedTo(ItemType newItem)...
Design and implement your own linked list class to hold a sorted list of integers in ascending order. The class should have member function for inserting an item in the list, deleting an item from the list, and searching the list for an item. Note: the search function should return the position of the item in the list (first item at position 0) and -1 if not found. In addition, it should member functions to display the list, check if...
Language: C++ Complete this function 1.Object &raw_front() { // Return the element at the front of the list *without* using the iterator classes // (You may assume the list is not empty) // Place your code here. Code: #ifndef LIST_H #define LIST_H #include using namespace std; template class List { private: // The basic doubly linked list node. // Nested inside of List, can be public // because the Node is itself private struct Node { Object data; Node *prev;...
13. Given the following structure struct node { struct node *next; int id; }; Write a code to insert a new node into the linked list as the last node of the linked list struct node *insertLast(stuct node **head, int newId) { } 14. Given the following structure struct node { struct node *next; int id; }; Write a code to insert a new node into the linked list after a node with the same id as the input parameter...
Please show me how to overload the operators << and >> #ifndef LINK_LIST #define LINK_LIST #include <iostream> using namespace std; template <typename T> struct Int_Node { T value; Int_Node<T> *pre, *next; }; template <typename T> class Link_List { template <typename U> friend ostream &operator<<(ostream &, const Link_List<U> &);// print all integers in the list template <typename U> friend istream &operator>>(istream &, Link_List<U> &);// input a value at the back of the list, like insert_node(val);...
Requirements Print a range Write a bag member function with two parameters. The two parameters are Items x and y. The function should write to the console all Items in the bag that are between the first occurrence of x and the first occurrence of y. You may assume that items can be compared for equality using ==. Use the following header for the function: void print_value_range(const Item& x, const Item& y); print_value_range can be interpreted in a number of...
