*:data3 -> data2 -> data1 -> NULL

*:I was asking the same question in today's class... just want to get clear about adding a Node. On your example, you wrote, that removing a Node is happenning from _head of the linked list... which is after data3 on my above example... right, then why we are adding a Node from tail (ie. between data1 and NULL) of the linked list...?? if the adding on tail is right then, why we are removing from other side i mean.. head??? both process suppose to happen from same place... right? If we get this type of question on test or exam, it will definetly cofuse me. Please correct me if I understand wrongly. Thanks! If the adding is happenning on head, here is my code...--[[User:Tvirutthasalam|Tvirutthasalam]] 19:08, 23 February 2012 (EST)
