Thread: I don't understand this error...

Okay I'm just writing a short piece of code to figure out a math problem

Code:

#include <iostream.h>

void main() {
	int num;
	int num2;
	int sum=0;

	cout<<"Enter num: ";
	cin>>num;
	
	num2=num*2;

	for (int i=1; i<num2; i++) {
		if (num2%i==0 && num%i!=0) {
			sum+=i;
		}
	}

	cout<<sum<<endl;
}

It compiles fine but it gives me the runtime error up to the part that inputs the data then crashes. Similary if i just put 1 statement in the main like "cout<<"blah"<<endl; then it still crashes:

Code:

Loaded 'ntdll.dll', no matching symbolic information found.
Loaded 'C:\WINDOWS\system32\kernel32.dll', no matching symbolic information found.
The thread 0x7C4 has exited with code 4373080 (0x42BA58).
The program 'D:\C++\MathTesting\Debug\test.exe' has exited with code 4373080 (0x42BA58).

the dead tree has a point. It would be best to change that "void" to an "int" before Prelude shows up...or you're in deep trouble...

[EDIT]
And for the well-being of everyone, make sure to return something. Preferably 0.

[EDIT]
Have I forgotten how to use Edit tags?? Or perhaps there are none and I'm just confused?...
[/EDIT]

I'm not too familiar with the topic of C++ specific headers, but I still think that my first suggestion was on the right track.

http://forums.devshed.com/t111869/s.html makes me feel better about my guess. It may just by a stylistic issue, but why use out of date headers?

Well (referring to the post below because it would've been a waste to make a new post for this), that's a tricky situation then.

This is just information telling you that if you ever have to debug down into the operating system that you're in for a rough time (no symbols you see). Other than that, these two messages can be ignored.
You can get rid of them by rummaging around on the Microsoft site somewhere (or your MSDN disks perhaps) for the latest symbol files for your OS.

Well that's the sort of garbage you get when you say void main.
Now do the job properly and finish with a return 0;
then the exit status will always be a nice successful 0

> void main and int main doesnt really matter for me since its just a test program
That kind of attitude will get you a long way - well just as far as the next "it doesn't matter to me" when in fact it "does matter to you".
Either you learn to do the job right each time out of habit, or you end up being roadkill on the information superhighway.

Thanks for the help but what i don't understand is why I never received these error messages before...? I've used void main a lot and I never get that exit garbage. In addition, I have never heard of this "no symbols" business; what does it mean? Is it because I reinstalled Windows with SP2? Is there any way to get rid of them? I see that the program runs fine but normally before, my programs, after execution, say "Press any key to continue" but now just closes on its own and produces those exit codes unless i stick it a getch() or pause thing. Odd
