实现原理
- 首先拿到所有桌面APP的路径。
- 然后将它们都存进结构体，并存入指针数组（前面的指向后面的）。
- 后面直接每次随机生成食物并且每次判断是否KO就行了。
- 感兴趣也可以看看C++贪吃蛇无尽模式。
代码实现（详见注释）
#include <bits/stdc++.h>

#include <commctrl.h>

// 大小与速度（速度越小越快）
const int S = 100, V = 300;
// 桌面
HWND D;
// 蛇的结构体
typedef struct Snake {// 位置 int x, y;// 蛇的第几节int idx;// 下一节struct Snake* nxt;
} node;
// 蛇头
node* head;
node* t;
// 目前食物的位置
POINT food;
// 目前吃了多少食物
int cnt, idx;
// 分辨率
int w, h;
// 共有多少食物
int sum;
// 找路径
char* Get() {LPITEMIDLIST pidl;LPMALLOC pShellMalloc;char s[200];if (SUCCEEDED(SHGetMalloc(&pShellMalloc))) {if (SUCCEEDED(SHGetSpecialFolderLocation(NULL, CSIDL_DESKTOP, &pidl))) {SHGetPathFromIDListA(pidl, s);pShellMalloc -> Free(pidl);}pShellMalloc -> Release();}return s;
