Well here is the complete code, that I am trying. since its been a long time since i have touched upon C programming, so somewhere i am making mistake in structure declaration. The problem goes here:-

1) I have declared a structure above and its object as array(buck[]).

2) Now when I declare this object array along with the structure, it works fine.. I have commented this thing right now.

3) But when I declare this object array inside the function.. because ultimately i have to declare inside function( as i need to build a recursive program, where objects will be created in very recursive call) then the program is throwing segmentation fault.

Expected Output

> [others@centos htdocs]$ ./a.out
> Strings: able aback a abet acid yawn
> yard yarn year yoke
> ****** 0 ****** 
> a = able aback a abet acid 
> b = 
> c 
> .
> .
> y = yawn yard yarnyear yoke 
> z =

Actual Output

[others@centos htdocs]$ ./a.out
Strings: able aback a abet acid yawn yard yarn year yoke
Segmentation fault

I have no idea, what difference I made in this. Kindly help.

Thanks.
