C ++使用模板写的一个List

template<class T> class List { private: struct Node { T data; Node *next; }; //head Node *head; //size int length; //process Node *p; //temp Node *q; public: List() { head = NULL; length = 0; p = NULL; } void add(T t) { if(head == NULL) { q = new Node(); q->data = t; q->next = NULL; length ++ ; head = q ; p = head; } else { q = new Node(); q->data = t; q->next = NULL; length ++; p -> next = q; p = q; } } void remove(int n) { if(n >= length ) { return; } length -- ; //删除头节点 if(n == 0) { q = head ; head = head -> next; delete(q); } else { q = head; for(int i = 0 ; i < n-1 ; i++) { q = q -> next; } Node *t = q ->next; q->next = q->next ->next; delete(t); } // p = head; if (p != NULL) { while(p->next != NULL) { p = p->next; } } } int getSize() { return length; } int getLength() { return getSize(); } T get(int n) { q = head; for (int i = 0 ;i < n ; i++) { q = q->next; } return q->data; } };

调用方式如下

List<Stu>list; Stu stu1; Stu stu2; Stu stu3; stu1.username = "1"; stu2.username = "2"; stu3.username = "3"; list.add(stu1); list.remove(0); list.add(stu2); list.add(stu3); for (int i = 0 ;i < list.getSize() ; i ++) { cout << list.get(i).username; }
