    <p>The code hangs while executing. Please help me to understand what is the problem here It stcks after the first travers and does not even enters the reverse function. Could not understand the issue: Help me on it.</p> <pre><code># include&lt;iostream&gt; # include&lt;stdlib.h&gt; using namespace std; struct sLL { int data; sLL * next; }; void createList(sLL ** head, int n) { if(n == 0) { return; } sLL * temp = (sLL *) malloc(sizeof(sLL)); if(temp != NULL) { temp-&gt;data = rand() % 100; temp-&gt;next = NULL; *head = temp; //head = &amp;(temp-&gt;next); createList(&amp;(temp-&gt;next), n - 1); } } void traverse(sLL * head) { cout&lt;&lt;"In traverse"&lt;&lt;endl; while(head) { cout&lt;&lt;head-&gt;data&lt;&lt;"-&gt;"; head=head-&gt;next; } cout&lt;&lt;"NULL"&lt;&lt;endl; cout.flush(); return; } sLL* reverse(sLL * head) { sLL * temp = NULL, * newNode = NULL; while(head) { newNode = head-&gt;next; // to traverse forword head-&gt;next = temp; temp = head; // Current node value which we use in next itr as a previous node value. newNode = head; // assigning newNode vlaue back to head so that we can traverse forward. } return temp; // final node value will be in temp i.e the current node value. } int main() { int n; sLL * head = NULL, *temp = NULL; cout&lt;&lt;"Enter the number of nodes :"; cin&gt;&gt;n; createList(&amp;head, n); cout&lt;&lt;"\nCreate Done"&lt;&lt;endl; traverse(head); cout.flush(); cout&lt;&lt;"Reverse Start"; temp = reverse(head); cout&lt;&lt;"reverse done"; traverse(temp); } </code></pre>

    3. CONarrow down the problem by selectively commenting things out until very few lines remain. That's call _debugging_ and will probably solve your problem for you...

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.
