This video is harmful. The code is totally wrong w.r.t. several points:

- Casting the result of malloc is useless.

- Allocated structs are of the wrong size.

- It is a miracle that its ultimate for works, the last pointer is not guaranteed to be NULL.

I was surprised as hell that his code actually does what he expected.

Please do not use youtube to learn programming, buy K&R.

Although the code is working, is has a severe and subtle problem: when allocating memory for a node, a wrong size is used, sizeof struct node *, which is 4 bytes (the size of a pointer).

The structure node itself is larger than 4 bytes, so when an element is created and initialized, the heap is corrupted. The program works because the memory is leaked (no free is performed), but in a serious application, this bug would create crashes and would be nearly impossible to find.

after the first for loop add

(clist--)->ptr= NULL;

to make the code work

very simple and well made video.

it would be great if you could explain your code also ... i mean like step wise how it works ... it would help me very much to understand how linked list works ...

thanks

i made a solution for it ...

put flag at the end of your program if you have a problem..

that is in a last for loop; flag++

then put if(flag==10) { break; } so temprorary solution but for now that's all i can do :D

thanks a lot i understood this topic because of you...

[anilari1991]

thanks for your help but last code is not working :D thanks a lot
