We hope that after your thesis, you'll choose Ada because you like it.

C bit manipulations may be implemented in (at least) 3 ways in Ada:

1) (packed) array of boolean, if you are really manipulating bits.

2) representation clauses, if you want to extract fields

3) modular types, if you really need both an integer meaning and
bit manipulation. This is like unsigned numbers in C, but I would
recommand you consider the other 2 ways before... just because you
are less familiar with.
