One-Way Linked-List C++

This is a simple implementation of a one-way linked-list in C++.

Functions

• OneWayLinkedList(): Constructor
• addBegin(int data): Add new node to the beginning of the list
• void addEnd(int data): Add new node to the end of the list
• void print(): Print all nodes
• void deleteAll(): Delete all nodes
• bool has(int data): Check has a node with a specific data in the list or not
• int getSize(): Get the size of the list
• Node* getNode(int data): Get the node by searching with data
• void deleteNode(int data): Delete a node with a specific data
• Node* getNodeByIndex(int index): Get the node by searching with index
• void deleteNodeAfterIndex(int index): Delete a node after a node with a specific index
• void deleteNodeBeforeData(int data): Delete a node before a node with a specific data
• void deleteNodeByIndex(int index): Delete a node with a specific index
• void deleteNodeAfterData(int data): Delete a node after a node with a specific index
• void deleteNodeBeforeIndex(int index): Delete a node before a node with a specific index
• int count(): Count number of nodes
• int countRecursive(Node* node): Count number of nodes with a recursive function
• Node* getFirstNode(): Get the first node
• Node* getLastNode(): Get the last node
• void reverse(): Reverse the list
• void reverseRecursive(Node* node): Reverse the list with a recursive function
• Node* getMiddleNode(): Get the middle node
• int OneWayLinkedList::hasNode(int data): Check there is a node with a specific data in the list or not
• int OneWayLinkedList::hasNodeRecursive(int data, Node* node): Check there is a node with a specific data in the list or not (with a recursive function)
• Node* mallocNode(int data): Maloc a new node

Usage

// Create new list
OneWayLinkedList* list = new OneWayLinkedList();

// Add some nodes
list->addEnd(1);
list->addEnd(2);
list->addEnd(3);
list->addEnd(4);
list->addEnd(5);
list->addEnd(110);
list->addBegin(100);

// Print all nodes
list->print();

// Print the size of the list
cout << "Size: " << list->getSize() << endl;

// Reverse the current list
cout << "Reverse the list" << endl;
list->reverse();

// Print all nodes
list->print();

// Reverse the current list with a recursive function
cout << "Reverse the list with a recursive function" << endl;
list->reverseRecursive(list->getFirstNode());

// Print all nodes
list->print();

// Print the middle node
Node* middle = list->getMiddleNode();
if (middle != NULL) {
    cout << "Middle node: " << middle->data << endl;
} else {
    cout << "Middle node: NULL" << endl;
}

// Print all nodes
list->print();

// Check has a node with a specific data in the list or not
cout << "Has 110: " << list->has(110) << endl;
cout << "Has 111: " << list->has(111) << endl;

// Get the node by searching with data
Node* node = list->getNode(110);
if(node != NULL) {
    cout << "Node data: " << node->data << endl;
} else {
    cout << "Node not found" << endl;
}

// Get the node by searching with index
node = list->getNodeByIndex(0);
if(node != NULL) {
    cout << "Node data: " << node->data << endl;
} else {
    cout << "Node not found" << endl;
}

// Get the node by searching with index
node = list->getNodeByIndex(60);
if(node != NULL) {
    cout << "Node data: " << node->data << endl;
} else {
    cout << "Node not found" << endl;
}

// Print count of nodes
cout << "Count: " << list->count() << endl;

// Print count of nodes (recursive)
cout << "Count (recursive): " << list->countRecursive(list->getFirstNode()) << endl;

// Print the first node
node = list->getFirstNode();
if(node != NULL) {
    cout << "First node data: " << node->data << endl;
} else {
    cout << "Node not found" << endl;
}

// Print the last node
node = list->getLastNode();
if(node != NULL) {
    cout << "Last node data: " << node->data << endl;
} else {
    cout << "Node not found" << endl;
}

// Delete all nodes
list->deleteAll();

// Print all nodes
list->print();

// Print the size of the list
cout << "Size: " << list->getSize() << endl;
