Thanks! it's working now. It makes sense: before I only gave one element as an argument, but instead I had to give an array with starting address &patom[0]. Now all variables in the struct are kept...

Now it's like this:


void initialpos(struct atom *name, int N)
{
int i;

for (i = 0; i < N; i++)
{
name[i]->x=drand48()*20;

I tried changing the function like that as well; but it still doesn't work.
Maybe I'm silly, but I just don't see it.

(and thanks for helping)


void initialpos(struct atom *name, int N)
{...

Hello,

i'm still trying to learn C, and I have a new question ;).

I want to declare a struct, and use a function to manipulate the entries. If I change the values within a function it's ok;...

Wow... that's fast and correct ;). Thans a lot!

Hello,





Since you all helped me so well the previous time, I have a second question for you. I think it's fairly simple, but for some reason I can't find the answer.

That's alright ... We all have our hiccups ;).

I started learning C++ a long long time ago (never finished it though), but just started learning C with a tutorial. The tutorial is not very elaborate, and I didn't know i could use cin cout as well...

Thanks. It's a bit silly I didn't think of it ... Well, now I'll never forget ;).

Thanks a lot to all of you; not only for this thread, but in all other threads you helped people. Much appreciated!

Thank you both for your answers! They were very useful.
Now I have another problem (after that, I'll try to be quiet ;) ).
