Hi.
I have this problem: I used Borland C++ Builder 6 to compile a program and the result was 43380 (witch is correct from my point of view) and I compiled the same .cpp file and I used the same in data with Borland C and it showed -22156.
I'm asking why is this difference between the result of the compilers because I used the same .cpp file and I entered the same variabiles to get a result?
They're both 0xA974 in hex, the only difference being
- one is being interpreted as either an unsigned 16 bit integer, or a 32 bit integer,
- the other is a signed 16 bit integer.

Yep, thought so - one's a new 32 bit compiler, and the other is a 16 bit fossil.
Of course, if your code was better written in that it didn't assume so much about say the range of int, then the problem wouldn't appear :)
I used an unsigned int so it should appear correct.
I will post the code below to show you the problem:
the bold instruction is the only instruction witch uses variabiles that can be over the range of int. As you can see I used especialy an unsigned int and the result is still -22156 for an: 84, luna: 11, ziua: 20.Code:...
I don't know why.
printf's %d is for signed integers, use %u instead.Quote:
printf("\n\ncod data: %d",cod);
> void main(void)
main returns an int.
> printf("\n\ncod data: %d",cod);
If you declared it as unsigned int, then you should really use %u to display it.
Edit: Damn - beaten by the alphabet again
I'm changing to @@Aardvark ;)
uuuu, magic :)
That worked. Thanks a lot.
I only need the result. I'm not interested yet in what main returns. thx anyway. (I saw you're avatar, hope you're not ........ed :) ).Quote:

It's not a question of what you're interested in. It's a question of what is right according to the C standard, and what just happens to work on your particular compiler.Quote:
