It has been said that C is a universal assembler. Sometimes I
think C++ is a class-based universal assembler. STL is a collection
of macros a class-based universal assembler. This is not evil. It
is often a useful view since such a perspective serves as a warning
to the developer about the risks associated with using C++ for
creating reliable software. Once a programmer accepts the reality
of those risks, she/he can successfully create high quality software.
Many of those risks are absent in Ada. However, Ada has risks that
are addressed better in C++. For example, access parameters in
Ada 95 functions permit modification of the content of a record
(struct). A C++ function can be defined with a const for the
function or the parameter to ensure that the function is a "query
only" function. For Ada programmers, the syntax is equivalent to
constant function F1 (A : access T) return Y;
which guarantees that no updating capability is possible in this
function (like a protected function), or
function F2 (A : access constant T) return Y;
which guarantees that no update of any part of A is permitted.
There are features of C++ which some might say are "better" than Ada.
The point is that comparing languages at this level is unprofitable. I
prefer Ada for any software that is important, but I can see a lot of
ideas in C++ and Eiffel that are attractive language features.
