战舰代码太多命中

Question

这个项目是使用数组制作一个2d战舰项目。如果你击中，它会产生一个＆＃34; X。＆＃34;如果它是向上，向下，向右或向左一个槽，那么它就是＆＃34; H＆＃34;为了热。如果距离它的两个位置，那就是＆＃34; W＆＃34; W＆＃34; W＆＃34; W＆＃34; W＆＃34; W＆＃34;为了温暖。 ＆＃34; C＆＃34;对于三个插槽来说很酷，而对于其他一切都没有。 每次我去测试我的代码时，它第一次完全正常工作，但之后它将每个输入标记为命中，当它应该标记为＆＃34; H＆＃34;，＆＃34; W＆＃ 34;，＆＃34; C＆＃34;或＆＃34; M。＆＃34;
