Body
I'm having a segmentation fault when I want to save a string in a dynamic array. I have a program that does this: User insert char "s" The program enters a loop and save strings in an array (name: cod). When user inserts char "t", it stops After that I save that array in the first position of a new dynamic array (name: vec). Then if user insert char "s" again The program enters a loop and save strings in an array. When user inserts char "t", it stops After that I save that array in the second position of a new dynamic array. and so one. This is my code: int main(){ <pre><code>char Cod[30][11]; char tmp[11]; char ***vec; int i = 0; strcpy (tmp, "p"); vec = (char *** ) malloc (sizeof ( char *) ); vec[0] = (char ** ) malloc (sizeof ( char *) * 30); do { scanf("%s", tmp); while( (strcmp (tmp, "p")) != 0){ strcpy ( Cod[i] , tmp ); scanf("%s", tmp); i++; } vec = (char ***) realloc (vec, sizeof ( char *) * (i + 1)); vec[i + 1] = (char ** ) realloc (vec[i + 1], sizeof ( char *) * (30)); vec[i-1] = (char **) Cod; scanf("%s", tmp); } while((strcmp (tmp, "s")) == 0); printf("%s", vec[0][0]); </code></pre> return 0; } This is the part of the code that work's: <pre><code>#include <stdio.h> #include <stdlib.h> #include <string.h> int main(){ char Cod[30][11]; char tmp[11]; int i = 0; strcpy (tmp, "p"); do { scanf("%s", tmp); while( (strcmp (tmp, "p")) != 0){ strcpy ( Cod[i] , tmp ); scanf("%s", tmp); i++; } scanf("%s", tmp); } while((strcmp (tmp, "s")) == 0); printf("%s", Cod[0]); return 0; } </code></pre>

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.
