[RESOLVED] The code compiles and has output successfully but segmentation fault

The contents are deleteted

Please use code tags. This is all but unreadable.

What is "DislinInit"? What is "DislinTwoPlots"? What is "DislinFinish"?

Take a closer look at this:

Code:

---

double* fit=new double[N];
for(int i=0; i<=N;i++)
  fit[i]=(p[2]*xdata[i]+p[1])*xdata[i]+p[0];

Sorry, i am very new to C++. The "Dislin" stuffs are actually a package using for plotting the graph, I have no idea how it works but was told to put them in the codes. I am sorry if the code is unreadable but I couldn't find the code tag buttom (if there is any).

Just to clarify what Viggy said, since you're very new, fit[N] isn't valid.

I think I should put i<N instead of i<=N, am I right?

Yep. Arrays are indexed from 0 to size-1.

Thanks!

you type the code tags in yourself:

[ code ]

//code . . . .

[ / code ]

Without the spaces look through this as well, cool stuff in there.... http://www.codeguru.com/forum/misc.php?do=bbcode#code

You can also hightlight the code and press the (somewhat unintuitive) '#' button.
