b. false

a.True.

Explanation:

To delete a node from linked list it is best to do it by using two pointers suppose say prev and curr. Iterating over the linked list while curr is not NULL and updating prev also.On finding the node to be deleted we will set the prev so that it points to the next of curr and after removing the link we will free curr from memory.

line of code for deleting a node in c++:-

prev->next=curr->next;

delete curr;  or  free(curr);

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
