This example works with a initialized to "yy" as well, or "yyxx". 
The chars not provided are initialized to 0 (rather than 255 if 
the variable weren't initialized at all). This seems like a nice 
way to reuse a large fixed buffer that initially has small 
relevant content, like `char[255] line = "hello";`

It doesn't initialize the entire array to 'y', so it's not 
treating "y" as the same as 'y'.
