I am only able to add characters to the elements of the array.
How do I add a string to `a[i][j]`, `i` and `j` being integers?

```
    char ** a = malloc(sizeof(char *) * 12);
    int i;
    for (i = 0; i < 12; i++) {
        a[i] = malloc(sizeof(char) * 2);
    }

```

When I try to assign `a[0][0]` a string value, it gives a compile error:
