我先是用的fgets后一提交零分，下载数据后在Dev-cpp上测也是对的，加上freopen也对，我看了题解发现dalao都用的gets或者getline，我就改成了gets就AC了

0分代码（用的fgets）:

测评结果

#include <cstdio>
#include <cstring>


char str[250];
int ans, dict[200];

int main() {
	for (int i = 0; i < 200; i++) dict[i] = 1;
	dict['b'] = dict['e'] = dict['h'] = dict['k'] = 2;
	dict['n'] = dict['q'] = dict['u'] = dict['x'] = 2;
	dict['c'] = dict['f'] = dict['i'] = dict['l'] = 3;
	dict['o'] = dict['r'] = dict['v'] = dict['y'] = 3;
	dict['s'] = dict['z'] = 4;
	fgets(str, sizeof(str), stdin);
	str[strlen(str) - 1] = 0;
	for (int i = 0; i < strlen(str); i++) {
		ans += dict[str[i]];
	}
	printf("%d", ans);
	return 0;
}
