这是我的程序，哪位高手帮忙看看哪里错了
我是按照这个思路写的:
某次称量结果为even，所有出现硬币为真；
某次称量结果为up，左边的不轻，右边的不重，不在上面的都为真；
某次称量结果为down，左边的不重，右边的不轻，不在上面的都为真；

#include <string.h>

	cin >> nCases;

			if (!strcmp(szCase [j][2],"even")){
				for (int k = 0; k < strlen(szCase [j][0]) ; k++){
					nState[szCase[j][0][k] - 'A'][2] = 1;

				int appeared = 0;
