This dynamically allocates an array of n pointers to char:

char **p;
int n = 42;

p = malloc(n * sizeof *p);

You can then access the array like any array:

int i;

// Initialize all pointers to NULL
for (i = 0; i < n; i++)
{
    p[i] = NULL;
}

Or use calloc() to automatically zero the allocated memory
