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.
