    <p>I am writing a C assignment for one of my university modules. I am trying to return pointers to two arrays (1 array from each c file) for use in a function in a different c file. I will then do the correct calculations on said arrays.</p> <p>The current problem i am facing:</p> <p><strong>Note: the code below has has been simplified to be more readable the main elements are still in place</strong> </p> <ol> <li>The assignment restricts the use of global variables</li> <li>one array is in a file mayday.c</li> <li>one array is in a file ships.c</li> <li>the function call is in a file system_handler.c</li> </ol> <p> I need to be able to return the arrays from 2 and 3, for use in function in 4.</p> <p>the code is:</p> <p>mayday.c</p> <pre><code>#include &lt;stdio.h&gt; #include "mayday.h" #include "rescue_assets.h" #include "ship.h" void assign_mayday_to_ships() { mayday_call* m_ptr; ship* sh_ptr; /*correct operations on the arrays */ } </code></pre> <p>ships.c</p> <pre><code> void read_ship_locations() { ship ships[10]; /* fill array methods removed */ ret_ship_array(ships); } ship* ret_ship_array(ship ships[]) { return ships; } </code></pre> <p>The function call i am trying to use the two array's with:</p> <pre><code>#include &lt;stdio.h&gt; #include "mayday.h" #include "rescue_assets.h" #include "ship.h" void assign_mayday_to_ships() { mayday_call* m_ptr; ship* sh_ptr; /*correct operations on the arrays */ } </code></pre> <p>The assign_mayday_to_ships will use pointers which will be results on the return array methods from mayday.c and ship.c but i am unsure how to implement this.</p> <p>Any advice will be appreciated.</p>

    1. COI dont understand what assign_mayday_to_ships() is supposed to do... Can you please clarify?

    2. CO@ScottyBauer i have not yet implemented it but basically a ship has a mayday call assigned to it, so i am going to pass in both arrays and match the mayday call to the ship based on the mayday info, i know how to do this but i don't know how to access the arrays.

    3. CO"The assignment restricts the use of global variables" What does that *mean*? That you *have* to use global arrays but cannot refer to them in your functions? That you *cannot* use global arrays, rather only local arrays and they must be passed to your functions as parameters? that you cannot use arrays *at all* and must instead use dynamic allocation?

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.
