While discussing (er, pushing) Ada with some C-coding co-workers today
I asked a question to which I knew the answer (always the best kind!):
 "Have you ever had a bug caused by accessing off the end of an
array?"  Well, of course, they all had to say yes.  Then I started
thinking of other bugs that they would have to admit to, and which
wouldn't occur in Ada.  Nothing new here (Ada prevents many bugs...),
but I thought it would be fun and useful to develop a group list as an
Ada advocacy tool.  For example:


Have you ever had a bug caused by accessing off the end of an array?

Have you ever had a bug caused by an implicit type conversion?

Have you ever had a bug caused by a variable getting set to a value
outside its designed range?

Have you ever had a bug caused by different type sizes on different
platforms?

Have you ever had a bug caused by mixing incompatible types?

Have you ever had a bug caused by passing parameters of incorrect
types?

Have you ever had a bug caused by passing parameters in an incorrect
order?

Have you ever had a bug caused by different data structure ordering on
different platforms?


And so on.  It might also be nice to have a section of "Have you ever
wished you could..." questions.

Anyway, such a list strikes me as a potentially useful piece of
advocacy, should anybody want to offer contributions.
