    <pre><code>/* * PURPOSE * Search if a string contains a string and print it out from there */ #include &lt;stdio.h&gt; void searchHaystack(char cHaystack[], char cNeedle[]); void showResult(int iOffset, char cHaystack[]); int main() { // Declarations char cHaystack[50], cNeedle[50]; // Input puts("Haystack:"); gets(cHaystack); puts("Needle:"); gets(cNeedle); // Call searcher searchHaystack(cHaystack, cNeedle); return 0; } void searchHaystack(char cHaystack[], char cNeedle[]) { // Declarations int iCntr, iCntr2, iFoundOffset; // Search the haystack for the first letter of the needle for (iCntr == 0; iCntr &lt; 50 &amp;&amp; cHaystack[iCntr] != '\0'; iCntr++) { if (cHaystack[iCntr] == cNeedle[0]) { iFoundOffset = iCntr; for (iCntr2 == 1; iCntr2 &lt; 50 &amp;&amp; (cHaystack[iCntr+iCntr2] == cNeedle[iCntr2] || cNeedle[iCntr2] == '\0'); iCntr2++) { if (cNeedle[iCntr2] == '\0') { showResult(iFoundOffset, cHaystack); } } } } } void showResult(int iOffset, char cHaystack[]) { int iCntr; // Print the substring char by char for (iCntr == iOffset; iCntr &lt; 50 &amp;&amp; cHaystack[iCntr] != '\0'; iCntr++) { printf("%c", cHaystack[iCntr]); } printf("\n"); } </code></pre> <p>Looking at my debugger I noticed that cHaystack[] and cNeedle[] aren't passed to searchHaystack properly as only the first char is conserved. How do I fix this? I haven't learned about pointers yet.</p> <p>Also, I'm getting this warning on all three for loops:</p> <blockquote> <p>statement with no effect</p> </blockquote> <p>What's up with that?</p>

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.

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