c语言建立静态链表（C++静态链表）

直接上代码了，说明看注释就可以：

利用静态成员构建链表

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 #include <IOSTREAM.H> class Node { public: Node(int val, Node* next):val(val),next(next){} //~Node(){cout<<"del "<<val<<endl;} static void showAll();//打印全部节点的值 static void insertHead(int);//头插 static void insertTail(int);//尾插 static void delHead();//删头 static void delTail();//删尾 static void clear();//清空 protected: int val; Node *next; static Node *head; private: }; Node* Node::head = 0; void Node::showAll(){//打印全部节点的值 Node *p = head; while (p) { cout<<p->val<<" "; p = p->next; } cout<<endl; } void Node::insertHead(int val){//头插 Node *p = new Node(val, head); head = p; } void Node::insertTail(int val){//尾插 Node *p = new Node(val, 0); if (!head) { head = p; return; } Node *q = head; while (q->next) { q = q->next; } q->next = p; } void Node::delHead(){//删头 Node *p = head; if (head) { head = head->next; delete p; } } void Node::delTail(){//删尾 if (!head) { return; } if (!(head->next)) { delete(head); head = NULL; return; } Node *p = head; while (p->next->next) { p = p->next; } delete(p->next); p->next = NULL; } void Node::clear(){//清空 Node *p = head; Node *q = 0; head = 0; while (p) { q = p; p = p->next; delete q; } } void main(){ Node::delHead(); Node::delTail(); Node::insertTail(2); Node::delTail(); for (int i = 0; i < 10; i++) { Node::insertTail(i + 1); } Node::delTail(); Node::showAll(); }

利用类模板构建链表
这有点类似于list<>：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 #include <iostream> #include <string> using namespace std; template<class T> class Node//创建一个类模板，一个可以放入任何类型节点的链表 { public: Node(T val, Node* next):val(val),next(next){} static void showAll();//打印全部节点的值 static void insertHead(T);//头插 static void insertTail(T);//尾插 static void delHead();//删头 static void delTail();//删尾 static void clear();//清空 protected: T val; Node *next; static Node *head; private: }; template<class T> Node<T>* Node<T>::head = 0; template<class T> void Node<T>::showAll(){//打印全部节点的值 Node *p = head; while (p) { cout<<p->val<<" "; p = p->next; } cout<<endl; } template<class T> void Node<T>::insertHead(T val){//头插 Node *p = new Node(val, head); head = p; } template<class T> void Node<T>::insertTail(T val){//尾插 Node *p = new Node(val, 0); if (!head) { head = p; return; } Node *q = head; while (q->next) { q = q->next; } q->next = p; } template<class T> void Node<T>::delHead(){//删头 Node *p = head; if (head) { head = head->next; delete p; } } template<class T> void Node<T>::delTail(){//删尾 if (!head) { return; } if (!(head->next)) { delete(head); head = NULL; return; } Node *p = head; while (p->next->next) { p = p->next; } delete(p->next); p->next = NULL; } template<class T> void Node<T>::clear(){//清空 Node *p = head; Node *q = 0; head = 0; while (p) { q = p; p = p->next; delete q; } } class Student//创建一个自定义的学生类 { public: Student(string name, int age,char sex):name(name), age(age), sex(sex){} void showInfo(){ cout<<"姓名:"<<name<<" 年龄:"<<age<<" 性别:"<<sex<<endl; } protected: string name; int age; char sex; private: }; void Node<Student>::showAll(){//学生类节点和其他基本数据类型不同，不能直接用<<输出，所以重载showAll() Node *p = head; while (p) { p->val.showInfo(); p = p->next; } } void main(){ for (int i = 1; i < 10; i++) { Node<int>::insertTail(i);//这时Node<int>称为一个用类模板生成的模板类 Node<float>::insertTail(i / 10.0f); Node<double>::insertTail(i / 10.00); Node<Student>::insertTail(Student("stu", i, 'F')); } Node<int>::showAll(); Node<float>::showAll(); Node<double>::showAll(); Node<Student>::showAll(); }
