Hey @ssmit_joshi
Mentioned in comments : https://ide.codingblocks.com/s/363267

but still if we write that head-> ,it automatically shows that which node u want to link with prev or next , but in that case only head->next is showing ,head->prev is not showing in linking

#5

Hey @ssmit_joshi
Don’t see that,its something that IDE provides(its called autocomplete) and its not 100%accurate, also its not a good practice to use autocomplete as you are training your mind to depend on it

see here of we add insert first then it is working fine ,but again if we run it then it is not inserting the element at first pls chechk

#9

but i m initialising that in every function then wts the difference

#10

Bro u are checking if head==NULL but u never initialized head with NULL
And some compiler will give u garbage locations instead of NULL if u don’t do that,so that’s why we have to initialize head with NULL always in the start:slight_smile:

#11

see here i have aproblem about single linked list the code is correct but in search function if the element is not found then how we have to do that so help me in that i am sending

Hey @ssmit_joshi
Initialize i=0 and flag=0 in search function

#14
