how about in c?

If it's on the stack you can't.

you'd have to resize it (providing it was allocated on the heap).

Code:

---

char * arr = NULL;
size_t elements = 10;

if((arr = malloc(elements * sizeof(char))) == NULL)
{
    /* error, exit */
   
}


/* set the array values, oops we need 11 elements */

if((arr = realloc(arr, (elements + 1) * sizeof(char))) == NULL)
{
    /* failed to resize array */
}else{
    ++elements;
    arr[10] = 'v';  /* some value */   
}

/* free the array */
free(arr);
arr = NULL;
