I've been told by a programmer who's worked extensively in both C and Ada
that this is not true -- in Ada, once the program compiles, there are very
few bugs in it. Ada was designed with the intention of turning what would
be run-time bugs in C into compile-time bugs, and it appears that it has
succeeded to a large extent.
