Yes, that's correct. I did not say it's an ideal situation. As Marin
said, it's a tradeoff.
In Ada you don't know the length of the string unless you store it
separately or use Strings.(Un)bounded.
In C, you have to find the length explicitly if you need it.
Of course there is nothing prohibiting you from doing the other thing
in both languages, except that the standard string processing is
geared towards the predominant method in each of the languages.
