    <p>There are a few issues with your program. The realloc() statement is not used correctly. I also prefer fgets() for getting a line. Here is my solution. This also uses realloc() to increase the allocation of the buffer lines so that you neither have to know the number of lines in advance nor do you have to read the file in two passes (faster that way). This is a common technique to use when you don't know how much memory you'll have to allocate in advance.</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; int main(void) { int lines_allocated = 128; int max_line_len = 100; /* Allocate lines of text */ char **words = (char **)malloc(sizeof(char*)*lines_allocated); if (words==NULL) { fprintf(stderr,"Out of memory (1).\n"); exit(1); } FILE *fp = fopen("coll.txt", "r"); if (fp == NULL) { fprintf(stderr,"Error opening file.\n"); exit(2); } int i; for (i=0;1;i++) { int j; /* Have we gone over our line allocation? */ if (i &gt;= lines_allocated) { int new_size; /* Double our allocation and re-allocate */ new_size = lines_allocated*2; words = (char **)realloc(words,sizeof(char*)*new_size); if (words==NULL) { fprintf(stderr,"Out of memory.\n"); exit(3); } lines_allocated = new_size; } /* Allocate space for the next line */ words[i] = malloc(max_line_len); if (words[i]==NULL) { fprintf(stderr,"Out of memory (3).\n"); exit(4); } if (fgets(words[i],max_line_len-1,fp)==NULL) break; /* Get rid of CR or LF at end of line */ for (j=strlen(words[i])-1;j&gt;=0 &amp;&amp; (words[i][j]=='\n' || words[i][j]=='\r');j--) ; words[i][j+1]='\0'; } /* Close file */ fclose(fp); int j; for(j = 0; j &lt; i; j++) printf("%s\n", words[j]); /* Good practice to free memory */ for (;i&gt;=0;i--) free(words[i]); free(words); return 0; } </code></pre>

    1. CO+1. I strongly recommend putting the semicolon which is the body of the `for` loop on a line on its own. When appended to the same line after the close parenthesis, it is too easily mistaken for a typo, or overlooked. Nominally, you could have several `'\r'` characters on a single line; it might matter (but more likely won't).

    3. CO@willus how did you decide on the value 128 for `int lines_allocated`?

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).
