Inventory System, getting a few errors

[lauraw487]

Hi, I'm rather new to programming and I'm working on an inventory management system for the class I'm in. Here are the directions for the assignment:

Your code need to have the following features, all accessible from a menu.

Add an inventory item to the data file. This will automatically sort the data too. (Insertion sort is the one you want, see the code in the folder to do this). This will update the number of items on the menu screen.
Search the inventory for an item by inventory number. This assumes the array is sorted (which it should be) and uses a binary search. If found, print the stored info, otherwise print 'not found'.
List the inventory on the screen in neat columns. Display it in chucks of 15 items with a pause in between.
Save the inventory to the datafile. It should also stay in memory. You can 'hardcode' the name of the file, as opposed to asking for it, that way it's always the same.

Here's what I have came up with so far, and the error that is coming up is "no matching function call to std::vector<std::basic_string...." at line 114.

Any help would be appreciated :)

You can iteretate a vector like this:
for (int i = 0; i != inventoryNumber.end(it); i++)

Two example of how:

for (vector<string>::iterator i = inventoryNumber.begin();
 i != inventoryNumber.end();
 i++)

or:

for (int i = 0;
 i < inventoryNumber.size();
 i++)

Thanks, I made a few changes so now it will compile, but the program itself isn't working as it should. Did you by chance notice any logic errors I made earlier in the program as far as loading and sending the information to the data file goes?

Here are the changes I made also,

 int invNumS;

            cout << "Enter the inventory number of the item to search: ";
            cin>> invNumS;

            for (vector<string>::iterator i = inventoryNumber.begin(); i != inventoryNumber.end(); i++)
               {
                    if (invNumS == inventoryNumber.size())
                {
                    cout << endl << "Data for item number " << invNumS << ":" << endl << endl;
                    cout << "Item description is: " << inventoryDescription.size() << endl;
                    cout << "There are " << quantity << " in stock and the price is " << price << endl;
                }

                else
                {
                    cout << "There is no item number " << invNumS;
                }
               }

            break;

Thanks!
