    You (Cecilia) could do that, but if you need to store the string it's
    because you want to use it later. Then you will most likely need to know
    how many of those 1000 positions are used and how many contain garbage.
    That is, you have to keep track of the actual length of the string
    separately. Since there are string types in the standard library that
    keep track of the length automatically, it's better to use them.
