C++

• Create a function to remove the item with the given item name from the inventory. The inventory should stay sorted by item name after the removal. The function returns true if the removal is successful and it returns false if there is no matching name item or the array is empty.

bool removeItem(InventoryItem list[], int& size, const char itemName[]);

• Sample test:

char itemName[] = banana;

if(removeItem(inventory, numberOfItems, itemName)== true)

{..}

main.h

#pragma once #include using namespace std; #include #include #include #include "item.h"

const int CAPACITY = 20;

void populateInventory(InventoryItem list[], int& size, const char fileName[]); void printInventory(const InventoryItem list[], int size);

int main(int argc, char ** argv); //add your function prototypes here

main.cpp

#include "main.h"

int main(int argc, char ** argv) { InventoryItem inventory[CAPACITY]; int numberOfItems = 0; char fileName[] = "items.txt";

populateInventory(inventory, numberOfItems, fileName);

//invoke your functions here to do what is required

printInventory(inventory, numberOfItems);

return 0; }

//add your funciton implementations here

void populateInventory(InventoryItem list[], int& size, const char fileName[]) { ifstream inFile;

char name[MAX_CHAR]; float price;

inFile.open(fileName);

inFile.get(name, MAX_CHAR, ':'); while(!inFile.eof()) { inFile.get(); //throw away the delimiter ':' inFile >> price; inFile.ignore(MAX_CHAR, ' '); //throw away ' '

strcpy(list[size].itemName, name);

list[size].itemPrice = price; size++;

inFile.get(name, MAX_CHAR, ':'); } inFile.close(); }

void printInventory(const InventoryItem list[], int size) { int colWidth = 20; cout << fixed; cout << setprecision(2);

cout << setw(colWidth) << "Item Name" << setw(colWidth) << "Item Price" << endl; cout << "-----------------------------------------------" << endl; for(int index = 0; index < size; index++) { cout << setw(colWidth) << list[index].itemName << setw(colWidth) << list[index].itemPrice << endl; }
