建立linked list最基本需要三個指標,head指向linked list的第一個struct,current指向目前剛建立的struct,prev則指向前一個struct,目的在指向下一個struct,對於未使用的pointer,一律指定為NULL,這是一個好的coding style,可以藉由判斷是否為NULL判斷此pointer是否被使用。 39行 current=(structlist*)malloc(sizeof(struct...
A node in the linked list contains two parts, i.e., first is the data part and second is the address part. The last node of the list contains a pointer to the null. After array, linked list is the second most used data structure. In a linked list, every link contains a connection...

struct node // structure name { int data; // your data node *next; // your pointer }; By the above syntax, now we have some understanding of how to create a simple linked list in C++ using structure. How linked list work in C++?
int data ; struct node *next ; } ; In the above-linked list syntax struct is the mandatory keyword to be used because with help of structure we can create custom data structure and as it is a node so node keyword is used so we are creating a data structure and in node, we have ...

A Linked List in C++ is a dynamic data structure that grows and shrinks in size when the elements are inserted or removed. In other words, memory allocated or de-allocated only when the elements are inserted or removed. Thus, it means that no memory is allocated for the list if there is...
