Please use code tags. This is all but unreadable.

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

Take a closer look at this:

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.

[gracinda710]

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

[MrViggy]

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.
