Question 3
The length of a linked list is the number of nodes in the list.

a. pointer
b. top
c. front
d. head

Question 7
Which of the following is a basic operation on singly linked lists?

a. ascending
b. ordered
c. sequential
d. linked

Question 13
What is the purpose of the following code?

while (current != NULL)
{
//Process current
current = current->link;
}

a. Insertion of a node
b. Traversal of a linked list
c. Selection of a node

You can use the pointer head of a linked list to traverse the list.
True
False

Question 18
In a linked list, if a new item is always inserted in the beginning or in the end of the list and the data we read is unsorted, the linked list will be unsorted.
True
False

Question 19

True
False

now what do you whant ??
do you need to check the answers or what!

[StuXYZ]

I think if you expect us to look at your homework, you should explain how your got to your answers.

Many of these questions are a bit vague and deliberately ambiguous , e.g. question 4.
Since there are only two points per node, you only update two pointers.

Anyway, you have at >5 wrong. So do some work and write some linked list so you understand this.

It looks like you're trying to get us to solve your homework for you. If you have specific questions about the theory or mechanics behind any one question, I'll be happy to help. I'm not going to solve specific homework problems for you.

I was just looking for someone to check my homework for me. I just wanted to know which answers were wrong so that I could correct them. I am actually having a lot of trouble with programming codes and questions. I cannot understand my teacher and everyone in class is always busy so I am trying to find help from here. I just want someone to check my homework. I don't know if I have questions because I don't know what's right or wrong.I do not need anyone to do my homework for me, I would just like some guidance.
