allocating bidimensional matrix

[kolkoo]

Well just for fun I decided to fix your reallocating issue and give you a few pointers ( hopefully valid ) First of all you have no need of the static variable and no need to save the length of strings because what you are reallocating is just an array of pointers to the malloced strings, you dont need to reallocate the strings just the array of pointers so all you need to save is count of elements inside which you already use the n parameter for :P Second mistake you have was the dereferencing of the list pointer , *list[n] which in fact dereferences list[n] but you actually need to dereference list and get its n-th element so a pair of brackets can be very useful here (*list)[n]. So the final code should look like this:

#include <iostream>
using namespace std;


void add(char ***list, int n, char *person)
{
*list=(char**)realloc(*list,(n+1)*sizeof(char**));
(*list)[n] = (char*) malloc (strlen(person) + 1);
strcpy((*list)[n], person);
}

int main()
{
char **list = NULL;
int n = 0;

add(&list, 0, "jack");
printf("list[0]: &#37;s\n", list[0]);

n++;

add(&list, 1, "jeff");
printf("list[1]: %s\n", list[1]);
free(list[0]);
free(list[1]);
free(list);
return 0;
}

Hope I helped
