利用C++编写简易宝可梦对战小游戏

最近想到了用C++写个小时候课间嘴上玩的那种宝可梦游戏，先试写了个demo，只有早期的三个宝可梦和基础招式，感兴趣的朋友可以再自己添加，也没有各种物防特攻数值啥的，等以后会搞图形化界面了再做个复杂的，功能完善的。

玩法就是选择宝可梦和电脑对战，除了攻击还有三次防御的机会，可以完全抵消对面这轮的攻击，增加了一点博弈的感觉（其实和电脑也没啥好博弈的）

上代码

#include<iostream>
#include<windows.h>
#include<ctime>
enum Type {normal,fire,grass,water};//定义招式与pokemon属性
struct Atk//招式结构体
{
    char name[20];//招式名
    int damage;//伤害
    Type type;//属性
    int speed;//招式速度
    int pp; //招式技能点数量
};
Atk def{"def",0,normal,10,3};//防御
struct pokemon//pokemon结构体
{
    char name[30];//名
    int hp;//初始血量
    int speed;//pokemon本身速度
    Type type;//属性
    Atk atk1;//招式1到4
