Hi everyone
Im a real newbie to this, so i guess ive prob done soemthing stupid...
My program has be working fine, and i was testing that various parts of it worked, and it was goingn ok. I had to restart the compiler/editor (borland c++ 3) and now when i try to tun the program it starts then quits instantly!
If i switch to the output screen it says "Abnormal Program Termination".
Its been working fine for ages, any ideas what could be wrong?
Post your code
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
its 1000 lines long....
isnt that a bit much to post
Yes, that's a bit much
But what's a newbie doing with a 1000 line program?
First thing, does it run outside the IDE? It may simply be running out of memory.
Are you for example assuming that malloc() always succeeds?

Ive been programming for 4 months now but i still think im a newbie... Its my major coursework piece for college so thats why tis longish.Originally posted by Salem

Nope, it wont work outside the IDE.
whatis malloc()? ive never used it before.
malloc() allocates memory based on the size given.
Eg --
char *t = malloc(sizeof(char)*5);
t would have enough space for 5 chars...I think
Have you got a debugger? Perhaps you should get one if you don't!
I use Borland Turbo C++ 3.0 (Old DOS based program).
It has everything in one, a debugger, compiler and editor all in one.
no errors are reported at all....
Well if you're going to post that much code, then I suggest
1. Make sure you've indented the code properly. See the samples in the FAQ for some typical examples of well indented code.
2. Use the "Attach file" at the bottom of the reply page to attach a copy of your source.
3. Don't expect quick miracles for such large amounts of code.
4. Get a better compiler. The standard of C++ which Turbo C++ 3.0 uses is quite far removed from what is current practice.
Try www.compilers.net and find Dev-C++

Are you sure you're not doing a return 1 somewhere in main(), which would make the debugger think it's not ended right?
Also, if the compiler gives you warnings, try to fix them, because they may have become fatal.
Just some suggestions, not sure what could cause a program to act that weird.

I say what I say, I mean what I mean.
IDE: emacs + make + gcc and proud of it.
ive been looking at an older version of my code that i had saved an comparing the differences, i seem to have managed to fix it.
Thank you, for trying to help me, sorry if i have wasted your time.
BTW i have to use Turbo C++ 3.0, my teacher says i have to...
ok, sorry about this, ive jsut stumbled on the exact casue of the problem.
It appears when i insert this line:
into this struct:Code:float price;
Code:struct car { char company_name[30]; char regAB[3]; char reg01[3]; char regXYZ[4]; long int mileage; char type_of_tyre[10]; int no_of_tyres; int dd; int mm; int yyyy; float price;//this is the one that makes it go wrong, it runs without it char comment[50]; };
any ideas why this could be?
Old DOS compilers have always been a bit funny about detecting when floating point support is required or not.
If you just have a declaration and something like scanf(), then it usually gets it wrong, and reports some "floating point not linked" message.
The hacky fix seems to be to declare a dumm global variable like
> BTW i have to use Turbo C++ 3.0, my teacher says i have toCode:double fix_my_broken_compiler = 1.0;
Yeah, and what does that tell you about the quality of the teacher?
Don't tell me, they use void main() as well.

ok, ill try that thanks...
btw i use cout<<, not scanf()
and yeah we used void main() (whats wrong with that)
nope that variable didnt fix it...

See the FAQ

I think you're going to have to attach the whole file then.
