Reason # %ld not to use void main()

[mrdarrett]

typedef struct{
int i, j;
} deStruct;

deStruct main()
{
deStruct k;

k.i = 0;
k.j = 10;
return k;
}

Crashes when running the compiled code. (I used the Borland C++ 5.5
free command line tools)

Spectacular, though.

deStruct main()

^^^^^^^^
main returns an int. This is an obvious error.

{
deStruct k;

k.i = 0;
k.j = 10;
return k;

main returns an int. Your code is obviously erroneous.

Yes, absolutely, of course it does return an int. And yes my code
does crash, as intended.

I was pondering why "void main(void)" shouldn't work. So, I thought,
if it's wrong to declare main as void, then it should be wrong to
declare main as arbitrary. That's what the deStruct structure (pardon
the pun) was intended to show. And crash it did...

Then you should have mentioned it in the body of your message.
If something is important enough to be your main concern, it should be
in the body of your message instead of the subject header, which tends
to be useless except for identifying threads.

What compiler/machine are you using?
It compiles and runs without error on gcc-mingw and msvc 2005 on
windows xp sp2/i386.

However, gcc-mingw DOES warn about main returning non-int.

I'm using the Borland C++ 5.5 free command line compiler.

I get a window popping up on XP... forgot the exact error. When I
return to work I can post it if you like...

Yeah, I crashed NT4 once with double main, in much the same spirit of
enquiry. I was rewarded with lots of blinkenlights. (A text screen
appeared, randomly filled, and the flash attribute bit was set on a good
many of the character positions.)

Wow, a double main! I'll have to try that sometime...

I tried a triple main, but it wouldn't even compile.
