    <p>Hey i have a vector in a header file(Inventory.h) along with a cpp(Inventory.cpp) file for the header file(Inventory.h). I cant figure out how to use the push and pop functions without creating a seperate function called add that looks like this.</p> <pre><code>vector&lt;string&gt;s Inventory ::add(string item) { inventory.push_back(item); return item; } </code></pre> <p>But doing this shows me an error:</p> <pre><code>Error 1 error C2511: 'void Inventory::add(std::string)' : overloaded member function not found in 'Inventory' c:\users\conor\documents\college\dkit - year 2 - repeat\dkit - year 2 - semester 1 - repeat\games programming\maroonedca2\maroonedca2\inventory.cpp 19 1 MaroonedCA2 </code></pre> <p>Here is my Inventory.h</p> <pre><code>#ifndef INVENTORY_H #define INVENTORY_H class Inventory { public: //Constructor Inventory(); //Methods. string add(); void displayInventory(); void showInventory(); private: //Data members }; #endif //INVENTORY_H </code></pre> <p>And my Inventory.cpp.</p> <pre><code>#include "Inventory.h" #include &lt;iostream&gt; #include &lt;vector&gt; // To enable the use of the vector class. #include &lt;string&gt; using namespace std; vector&lt;string&gt; inventory; vector&lt;string&gt;::iterator myIterator; vector&lt;string&gt;::const_iterator iter; Inventory::Inventory() { } vector&lt;string&gt;s Inventory ::add(string item) { inventory.push_back(item); return item; } void Inventory:: showInventory() { char input[80]; cin &gt;&gt; input; char inventoryRequest[] = "i"; int invent = strcmp (input,inventoryRequest); //compare the player input to inventoryRequest (i) to see if they want to look at inventory. if(invent == 0) { displayInventory(); } } void Inventory:: displayInventory() { //vector&lt;string&gt; inventory; cout&lt;&lt; "You have " &lt;&lt; inventory.size() &lt;&lt; " items.\n"; cout &lt;&lt; "\n******Inventory******"; cout&lt;&lt; "\nYour items:\n"; for (int i= 0; i&lt; inventory.size(); ++i) cout&lt;&lt; inventory[i] &lt;&lt; endl; } </code></pre> <p>If i could get help with this function or a solution to using the push/pop in my main whilst in the header file it would be appreciated. Thanks in advance.</p> <p>Edit: New Errors.</p> <pre><code>Error 1 error C2146: syntax error : missing ';' before identifier 'add' c:\users\conor\documents\college\dkit - year 2 - repeat\dkit - year 2 - semester 1 - repeat\games programming\maroonedca2\maroonedca2\inventory.h 17 1 MaroonedCA2 Error 2 error C4430: missing type specifier - int assumed.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
