I think I did what everyone said in my other thread and once again, reduced a bunch of errors. I started with 200+ errors but I'm down to around 40. Most of it has to do with the output part in my first function in my cpp file. Another part that is giving me problems now is the last function. I have the errors of that function in the code. My compiler tells me that most of my errors are in the cpp file.Here is what I have now:
header file:
main file:Code:#include <string> #include <iostream> #include <vector> #include <iomanip> #include <fstream> using namespace std; class inventoryItem { private: int quantity; //the variable that represents number of items currently in stock int cost; //the per-unit price of the item int totalCost; //total inventory cost of the item string itemNumber; //a variable that is set when the item is created public: /*adds a new item and set itemNumber along with quantity and cost*/ inventoryItem( string n, int q, double c ); inventoryItem::inventoryItem ( string n, int q, double c ) :itemNumber(n), quantity(q), cost(c) void string erase(string n) {itemNumber = n;} //it will delete the item number void setQuantity(int q) {quantity = q;} //modifies the quantity of inventory void setCost(double c) {cost = c;} //modifies the cost of the inventory int getItemNumber() {return itemNumber;} //gets the item number of the inventory int getQuantity() {return quantity;} //gets the quantity of the inventory (sold) int getQuantity2() {return quantity2;} //gets the quantity of the inventory (delievered) double getCost() {return cost;} //gets the cost of the inventory double getTotalPrice(); //cost*quantity };

I don't understand why it said erase is not part of inventoryItem. I have it in my header file.Code:add 123456789123 12.65 50 add 123456789123 12.65 50 add 123456789124 12.65 50 add 123456789125 12.65 50 add 123456789126 12.65 50 delivered 123456789123 50 delivered 123456789123 1 sold 123456789123 2 delivered 123456789123 1 sold 123456789123 100 sold 123456789123 99 sold 123456789123 5 remove 123456789124 sold 123456789124 5 delivered 123456789127 50 sold 123456789128 50 priceChange 123456789123 10.99 priceChange 123456789128 10.99 remove 123456789128
