本蒟蒻根据Dev C++ 工具里提供的源代码改编的小程序

虽然本蒟蒻啥也没看懂，只是把现成代码改了改

上代码 c++ TDM-GCC 4.9.2：

#include <windows.h>
#include<cstdio>
#include<cstring>
void movew(int *x,int *y,int *xk,int *yk,bool *ux,bool *uy,bool *uxk,bool *uyk,int k){
    //x变化 
        if(*uxk){
            *xk=*xk+k;
        }
        else{
            *xk=*xk-k;
        }
        if(*xk>=1366-150){
            *uxk=false;
        }
        else if(*xk<=0){

        }
        //y变化

效果：两个空白窗口在屏幕上蹦迪

问题：开始蹦迪之后，如果点击任意一处，就会死机，目前还不知道怎么解决，望各位大佬们看看。

关闭方法：关掉黑色窗口即可

本蒟蒻的程序变量名很迷惑，麻烦各位大佬了

各位大佬们，如果有懂得，麻烦看看那个问题，谢谢了
