Segmentation fault somewhere

#1


can you please tell me why this code isnt working

#2

Hi… u are not building the linked list only correctly… refer this https://ide.codingblocks.com/s/608567

#3

but i still dont get what was wrong with my code…why was i getting a segmentation fault??

#4

can you please elaborate the step where i was wrong

#5

https://ide.codingblocks.com/s/608675 i have corrected ur code…
and i highly suggest u to go and watch video lectures on building linked list as it is not possible to explain the same here…

#6

I did check the videos- my logic was same just a slight difference in implementation which I think you are suggesting. I got the building logic - you are adding the nodes from the end I was adding them from head. but it still doesn’t explain exactly which expression was causing the segmentation fault :frowning:

#7

firstly according to ques we have to insert nodes at end and not in front…
secondly in main function when u declared head initialize it with NULL.
and whenever u create a first node u have to handle the base case as i have shown my code… rest if u still are not getting it i suggest u to dry run it using pen and paper u would get a better insight
