    <p>This code is driving me up the wall. The goal is to split to char[] based on a comma. It works in java. But prints weird output in C. The error I suspect is at 28 on the second iteration of the loop where I tried to add 5 the array turns into weird characters.</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;string.h&gt; main() { char asshat[] = {'4','5','5',',','7','4','7','\0'}; int firstSize = 0;// int secondSize = 0;// //new = 4 \0 \0 char first[] = {'0', '\0'};// //new = char second[] = {'0', '\0'};// char *first_ptr = first; char *second_ptr = second; int takingFirst = 1; int takingSecond = 0; int i; for (i = 0; i &lt; strlen(asshat); i++) { if (asshat[i] != ',') { if (takingFirst == 1) { first_ptr[firstSize] = asshat[i];//ERROR here when you add 5 you s**t bricks firstSize++; if (asshat[i+1] != ',') { char new[firstSize+2]; int k; for (k = 0; k &lt; strlen(first_ptr); k++) { new[k] = first_ptr[k]; } new[firstSize] = '0'; new[firstSize+1] = '\0'; first_ptr = new; } } if (takingSecond == 1) { second_ptr[secondSize] = asshat[i]; secondSize++; if (asshat[i+1] != '\0') { char new[secondSize+2]; int k; for (k = 0; k &lt; strlen(second_ptr); k++) { new[k] = second_ptr[k]; } new[secondSize+1] = '\0'; second_ptr = new; } } } else { takingFirst = 0; takingSecond = 1; } } printf("%d\n",strlen(first_ptr)); printf("%c%c%c\n",first_ptr[0],first_ptr[1],first_ptr[2]); printf("%s\n",first_ptr); printf("%d\n",strlen(second_ptr)); printf("%c%c%c\n",second_ptr[0],second_ptr[1],second_ptr[2]); printf("%s\n",second_ptr); } </code></pre>

    2. COStart again from scratch. I know how to do this and your solution does not get anywhere near it. Which C book are you learning from?

    3. COThink simple. First compute where `,` is occurring in the sequence. From it's index, you know the size of the two char arrays( +1 for `\0` termination character) to be `malloc`. It doesn't hurt to use `C++` key words in `C` but I would rather consider it as a bad practice.

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.
