struct grade
{
char name[20], ID[10]
int maths, english, physics;
grade *next;
};
grade *CreateList()
{
grade *head = NULL, *temp = NULL, *tail;
printf("输入学生成绩信息，在学号处输入-1结束输入。\n\n");
while(1)
{
temp = new grade;
printf("输入学号：");
scanf("%s", temp->ID);
if(!strcmp(temp->ID, "-1"))
{
delete temp;
break;
}
printf("输入姓名：");
scanf("%s", temp->name);
printf("输入数学成绩：");
scanf("%d", &temp->maths);
printf("输入英语成绩：");
scanf("%d", &temp->english);
printf("输入物理成绩：");
scanf("%d", &temp->physics);
if(head == NULL)
{
head = temp;
head->next = NULL;
