vc++相关程序问题

Question

vc++相关程序问题以及其结构体与简单链表实践相关问题……谢谢了……

Answer 1

代码及运行结果如下：

#include <iostream>
#include <cstring>
using namespace std;

struct node
{
    int num;//学号
    double CPP;//成绩
    node* next; //指向下一个节点的变量指针
};

node* creat()
{
    int n, i;
    node* head = 0, * p, * t=0;
    cout << "请输入链表的长度：";
    cin >> n;
    for (i = 0; i < n; i++)
    {
        p = new node;
        cout << "请输入第" << i + 1 << "个学生的学号：";
        cin >> p->num;
        cout << "请输入第" << i + 1 << "个学生的成绩：";
        cin >> p->CPP;
        p->next = 0;
        if (head == 0)
        {
            head = p;
            t = head;
        }
        else
        {
            t->next = p;
            t = p;
        }
    }
    cout << "链表创建完成！" << endl;
    return head;
}

void print(node* head)
{
    node* p = head;
    cout << "显示链表数据：" << endl;
    while (p)
    {
        cout << "学号：" << p->num << "\t成绩：" << p->CPP << endl;
        p = p->next;
    }
}

void release(node* head)
{
    node* p;
    cout << "释放链表" << endl;
    while (head)
    {
        p = head->next;
        delete head;
        head = p;
    }
    head = 0;
}

int main()
{
    node* head = creat();
    print(head);
    release(head);
    return 0;
}
