Question

I am trying to define a dynamic array containing char pointers that point to strings. The string can be of any length, so i used char pointers. I want to dynamically resize the array each time I need to store more values. The following code gives me segmentation fault. Am I doing it well?

int main() {
    char **input=NULL;
    char *buffer;

    int i=0;

    do {
        input = (char **)realloc(input, (i+1) * sizeof(char *));

        scanf("%s", &buffer);
        strcpy(input[i++],buffer);

    } while(strlen(buffer)!=0);


}

Answer 1

Your buffer and your input[i] are not allocated.
