Thread: Dynamic array of pointers

Hi. I'm learning about pointers and as an exercise I'm trying to create a program that will store an unknown number of pointers to strings that will be input by the user in an array of pointers.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(void)
{
    char input[100];
    char **strings;

    do {
        printf("Type something: ");
        fgets(input, sizeof(input), stdin);

        /* I don't know what to do now */
    } while (strcmp(input, "exit") != 0);

    /* free the memory that was allocated */

    return 0;
}

If I was using something like

Code:

char *strings[5000];

then I'd know what to do but using **strings is confusing me. Anyone can give me a hint? Thanks.
