Though I can't image the reason to put this question on this forum,
here's what I think:

'Static' is normally reserved to specify the data should never be
destroyed by the compiler if the compiler thinks it's not necessary any
more (eg. to make data 'static', i.e. available between function calls to
the same function).

'const' means the program shouldn't be able to change it. Like you said,
make it read-only.
