Hello, for a school assignment I was supposed to write an insertion sort algorithm for a doubly linked list. As the feedback system of this particular course is rather weak (actually non-existent) I would like to ask you for your honest opinion about how well this is implemented, what could be improved, made more efficient, etc? Thanks in advance, Marcel #include <iostream> using namespace std; class elem{ public: int value; elem* prev; elem* next; elem(int e, elem* ptr1, elem* ptr2){ value = e; prev = ptr1; next = ptr2; }; }; class list{ private: elem* first; elem* last; int length; …

My Objective is to define a function, with a pointer to a list of elements of the structure I created as the first parameter, a C-character string (of type char * ) as the second parameter and one of the of the two values,num or name, from the above enumeration type as the third parameter. In the body of this function, all elements of the complete list in the first parameter are to be checked whether -by calling the function the bool function isPartof and create a new list with all the hits(matches) found. Finally Return the head of this …

I'm working on this code for class, I am not expecting anyone to do my homework but help would be appreciated. Nodes are confusing for me and my professor did not explain well. The errors I am getting are where I declare the functions, I dont know the nodeType(?) that goes in the arguments. Hopefully that makes sense.I think I may have also need to initialize the node? #include <iostream> #include <fstream> #include <string> #include <iomanip> using namespace std; ///employeeType struct, node struct, typedef statement go here. struct employeeType { int idNum; string firstName; string lastName; char gender; double payrate; …

HI I donot understand where to start . I need ideas and help. void InsertList(c4735list *destinationList,c4735list *sourceList,node *startNode) { //=====================not implementd yet } this fn inserts source list into destination list.the nodes are inserted after the startnode in destination list.source list should be an empty list after this operation. the current pointer should be set to the head of the list. typedef struct _node { struct _node *prev, *next; void *data; } node; typedef struct _c4735list { node *head, *tail; node *current; void (*cleanupData ) (void *); // function that knows how to clean up data } c4735list;

Hello All. Been playing around with some linked dropdowns. It seems to be a recurring theme here on DW, so I thought I'd offer this up as a possible solution or for discussion, to see how it could be improved. The premise for this set of linked dropdowns is that it is not dependent on php or Ajax following page load, that is to say, all the data is initially dumped into json format from the database and then everything is left to javascript. I've used jQuery to produce a plugin, but the same functionality is possible with just plain …

I'm new to C and I i have an assignment where I have to build a dictionary (Linked List). Basically the user inputs several words,year and their definitio likn this: Example: > love_#_2004_#_LOVING `trade_#_2001_#_INVEST` etc... Now what I need is to have a function that will scan the definition which is in UPPER CASE and give me back the word it relates to. Example: What word would you like to search? Input: INVEST Output: Found "INVEST" in the word "trade". I was kind of answered to that question. It helped understanding what was done but it's unfortunately not enough. The …

This is an example of a singly linked list allowing you to enter a number of names and associated ages. The twist is that the names are inserted into the list in ascending order. When the list is displayed, it is already sorted by name. Note: This is not an exercise in safe data input. While precautions have been taken, any fool can stress the language easily.
