如何定义一个指向NPC的指针，
struct NPC * pn;
用户在终端输入npc的数量，动态分配npc的空间
#include <stdio.h>
#include <stdlib.h>
typedef struct _NPC{
char name[20];
int hp;
int act;
}NPC;
typedef struct _NODE{
NPC data;
struct _NODE * pNext;
}NODE;//一个节点
NODE * head=NULL; //定义头结点
void addNODE(){
if (head==NULL) {
head=malloc(sizeof(NODE));
printf("请输入NPC信息名字 hp act");
scanf("%s %d %d",head->data.name,&head->data.hp,&head->data.act);
head->pNext=NULL;
}else{
NODE * p=head;//p指向头节点
while (p->pNext!=NULL) {
p=p->pNext;//p指向下一个节点
}
p->pNext=malloc(sizeof(NODE));
p=p->pNext;
ottom:0px; font-size:18px; font-family:Menlo; color:rgb(201,&head->data.act);
p->pNext=NULL;
}
printf("添加节点成功\n");
}
void printNODE(){
NODE *p=head;
while (p!=NULL) {
printf("NPC名字 %s hp %d atc %d\n",p->data.name,p->data.hp,p->data.act);
p=p->pNext;
}
printf("输出所有节点成功\n");
}
void insertNODE(){
//创建一个新节点
NODE * newNODE=malloc(sizeof(NODE));
printf("请输入NPC的名子 hp act\n");
scanf("NPCdata.name,&newNODE->data.hp,&newNODE->data.act);
printf("请输入插入到第几个节点之后\n");
int index;
int count=0;
NODE * p=head;
scanf("%d",&index);
while (p!=NULL) {
count++;
if (count>=index) {
break;
}
p=p->pNext;
}
NODE *p2=p->pNext;
p->pNext=newNODE;
newNODE->pNext=p2;
printf("插入节点成功\n");
}
void deleteNODE(){
int index;
printf("请输入要删除第几个节点\n");
scanf("%d",&index);
int num=0;
NODE * p=head;
while (p!=NULL) {
num++;
p=p->pNext;
}
if (index==1) {
p=head;
head=head->pNext;
free(p);
}else if (index==num){
NODE * p=head;
while (p->pNext->pNext!=NULL) {
p=p->pNext;
}
free(p->pNext->pNext);
p->pNext=NULL;
}else{
int count=1;
NODE * p=head;
while (p!=NULL) {
count++;
if (count==index) {
break;
}
p=p->pNext;
NODE * p2=p->pNext;
p->pNext=p2->pNext;
free(p2);
}
printf("删除节点成功\n");
}
}
void modifyNODE(){
int index;
printf("请输入有修改的节点\n");
scanf("%d",&index);
NODE * p=head;
int count=0;
while (p!=NULL) {
count++;
if (count>=index) {
break;
}
p=p->pNext;
printf("请输入NPC的名字 hp act\n");
scanf("%s %d %d\n",&p->data.hp,&p->data.act);
}
printf("修改节点");
}
int main(int argc,const char * argv[]) {
printf("NPC管理系统\n");
int menuselect;
while (1) {
printf("1.添加NPC节点\n");
printf("2.输出所有NPC节点\n");
printf("3。插入NPC节点\n");
printf("4.删除NPC节点\n");
printf("5.修改NPC节点\n");
printf("6.退出\n");
scanf("%d",&menuselect);
switch (menuselect) {
case 1://添加节点
addNODE();
break;
case 2://输出节点
printNODE();
break;
case 3://插入节点
insertNODE();
break;
case 4://删除节点
deleteNODE();
break;
case 5://修改节点
modifyNODE();
break;
case 6://退出
return 0;
break;
default:
break;
}
}
return 0;
