Request help in c++. Please no vector or algorithm library. Here are the classes: class PriceHistory{ public: // members float historicalPrice; string date; // user enters in the form YYYY-MM-DD // mutators void setHprice(float); void setDate(string); // accessors float getHP() const; string getDate() const; }; class Grocery{ public: // Array size for price history objects string description; int upc; float cost; float price; int inventory; char status; // counter for grocery items static int numGroceryItems; PriceHistory priceHistory[PH_SIZE]; // counter for history items int numHistItems; // accessors string getDescription() const; float getUpc() const; float getCost() const; float getPrice() const; int getInventory() const; char getStatus() const; int getHistItems() const; // mutators void setStatus(char); void updateGroceryItems(); }; Here is what i need help: Phase 2 Transaction processing phase. Main asks the console user for transactions. Use getline; do not use some other form of input. H upc date price Add a price history to the grocery item with UPC code upc. The upc, date, and price fields are fixed in size and separated by blanks. Perform a linear search for the item. If its found, add the history and display a success message. If the UPC isnt found, display a not found message. You may assume that you will never add more than 25 history items per grocery item. C upc1 upc2 Compares the number of price history elements for the two items specified by upc1 and upc2. If the number of elements is equal, display a message saying they are equal. Otherwise, display a message saying they are not equal. Use an operator== overload to implement the comparison. If either upc is not found, display an error message. X Clean up and exit..
