if i create an array of pointers to a structure "struct node" as:

```nohighlight
struct node *r[n];

```

and create "n" number of "linked lists" and assign it to the various struct pointers r [i]using some function with a return type as structure pointer as:

```nohighlight
r=multiplty(.......) /*some parameters*/

```

is it wrong to then use the individual array members like r[0],r[1] (which are now pointers to various linked lists) etc. as parameters to a function that accept a structure pointers as parameter like::

```nohighlight
struct node *add_result;
add_result= add(r[o],r[1]);/*add() returns a struct pointer,no error shown in compilation */

```

the programme goes into an infinite loop whenever i try to display the list pointed by add\_result..the functions add() and display() work fine in other cases..

There's no problem with that syntax, whatever is going wrong is something else.

Seeing the contents of these functions could be instructive.

Can you post this piece of code...seems like the condition for stopping the display pointed by add\_result may not be right.
