The program probably printed out 30 elements, 20 of which were garbage.
If you ask C to read or write beyond the ends of an array, it will try
to comply. If you are reading, it will give you the contents of some
other piece of memory. If you are writing, it will change the
contents of some other piece of memory, probably causing a problem
elsewhere in your program.
