    <p>A program dealing with graphs(from graph theory) representation and transformation.The adjacency list and matrix are implemented like dynamic arrays of vectors(don't ask why not vector of vector) for the following function program exits with memory error and compiler pointing to the orphan vector definition.</p> <pre><code>int vertex,edges; vector&lt;int&gt; *adjacencyList,*adjacencyMatrix; void listToAdMatrix(int vertexNumber, vector&lt;int&gt; *List, vector&lt;int&gt; *Matrix){ int in=0,cont=0; for(int i=0;i&lt;vertexNumber;i++){ in=i; for(auto j=List[in].begin();j!=List[in].end();j++){ for(int k=0;k&lt;vertexNumber;++k){ if(k==*j) Matrix[cont].push_back(1); else Matrix[cont].push_back(0); } cont++; } } } //function call //vertex(number) and ajacencyList are initialized adjacencyMatrix=new vector&lt;int&gt;[vertex]; listToAdMatrix(vertex,adjacencyList,adjacencyMatrix); </code></pre> <p>The "source of error" in STL where compiler points:</p> <p><a href="http://i51.tinypic.com/2dt0t9e.jpg" rel="nofollow">http://i51.tinypic.com/2dt0t9e.jpg</a></p> <hr> <p>The error message:</p> <p><strong>Unhandled exception at 0x001a543b in graph.exe: 0xC0000005: Access violation reading location 0xfdfdfe01.</strong></p> <hr> <p>the fillList function used to fill the adjacency list :</p> <pre><code>void fillList(int vertexNumber, vector&lt;int&gt; *List){ int input=0; for (int i=0;i&lt;vertexNumber;i++){ int in=i; cout&lt;&lt;"Introduce adjacent vertexes for the vertex -"&lt;&lt;i+1&lt;&lt;"-:"&lt;&lt;endl; for(int j=0;j&lt;vertexNumber;j++){ std::cout&lt;&lt;i+1&lt;&lt;"-"; std::cin&gt;&gt;input; if(input==0) break; List[i].push_back(input-1); } } } </code></pre> <p>Any clue is welcome.</p> <hr>

    2. COWe need to see more of your code. When I compile and run this(initializing vertex to 10, and adjacencyList to an array of the same size), there are no errors.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
