Variable expansion happens first:
someprog --greeting Hello Karsten
then tokenising, so someprog get three arguments:
1. --greeting
2. Hello
3. Karsten
whereas you want it to get two arguments:
1. --greeting
2. Hello Karsten
in which case you need double quotes around $C to prevent it from being
split into multiple tokens:
someprog --greeting "$C"
