打了好久代码，但所有数它都输出

是 switch 语句错了吗？？求挑错！！

~~有点乱，大佬们忍一下。。~~

~~最后一个RE我也不知道怎么回事。。~~

@tangjiayang 直接把所有要显示出来的数存在数组里不香吗？

by HYdroKomide @ 2021-10-06 15:13:18

@tangjiayang 然后直接输出数组

by MCH_Satrimiten @ 2021-10-06 15:14:58

@tangjiayang 您每次都存在一个地方啊？

by ttkuilei @ 2021-10-06 15:15:21

@Kevin_FOS 我就是这么编的代码。。。

by ttkuilei @ 2021-10-06 15:16:27

@MCH_Satrimiten

int k=4*i-3;

~~心态崩了~~

by HYdroKomide @ 2021-10-06 15:42:38

@tangjiayang 不，我的意思是：

const string a[5][10]={"XXX","..X","XXX","XXX","X.X","XXX","XXX","XXX","XXX","XXX",
                       "X.X","..X","..X","..X","X.X","X..","X..","..X","X.X","X.X",
                       "X.X","..X","XXX","XXX","XXX","XXX","XXX","..X","XXX","XXX",
                       "X.X","..X","X..","..X","..X","..X","X.X","..X","X.X","..X",
                       "XXX","..X","XXX","XXX","..X","XXX","XXX","..X","XXX","XXX"};
