Ada Leaking Into Day Job

Ada Leaking Into Day Job

[Warren]

Heh, heh... today I got several COBOL compile
errors, telling me that Ada is leaking into my
day job:

    ...
    END EVALUATE

(Should be END-EVALUATE)

    IF RET-CODE /= 0 THEN

(you get the idea). I never had this problem with
C/C++ :)

I wonder how many programmers have had Ada leak into their C/C++ and
have written something like

   if (code /= 0) { ... }

This is valid C, so the compiler won't complain, but it will not quite
do what you want.

Are you sure? ;-)

int main(int argc, char** argv) {
   int code = 1;
   if(code /= 0) {
      return 1;
   }
   return 0;
}

[beorn@hactar tester]$ LANG=en gcc ada_not_equal.c 
ada_not_equal.c: In function 'main':
ada_not_equal.c:3: warning: division by zero

That's even without the otherwise indispensable -Wall.

The problem I have most often when I switch languages is that I get =, := 
and == mixed up.

It is more the "Ada style" that has leaked in my VB coding, like

    Sub Mix(ByVal code As Char, ....
        ' declarations here and not scattered anywhere...
        Dim li As String
        Dim bid As String
        Dim fi, fo As Integer
        Dim first_line As Boolean
        ' begin
        first_line = True
        '
        fi = FreeFile()
        FileOpen(fi, name_1, OpenMode.Input)
        While Not EOF(fi)
          ...

Now I've simplified things, making GCC leaking itself into the day
job :-).

Yep, I've been having to backspace over some := in my
awk scripts lately also.

Yeah, I had one of these drive me bonkers for a while:

for (i = 0; i < something; i++);
    {
         /* something here */
    }

Always executed ONCE...  Even when it wasn't supposed to! :-(

That's more a typical C annoyance (there was a funny list about that).
Should not come from typing Ada code (not ';' after for ... loop)

A nice of such lists: "The Top 10 Ways to get screwed by the "C"
