我的14,15行是
freopen("sample_data.in","r",stdin);
freopen("sample_data.out","w",stdout);
m.c:14: error: expected declaration specifiers or ‘...’ before string constant

我的14,15行是
freopen("sample_data.in","r",stdin);
freopen("sample_data.out","w",stdout);

这两行应该放在函数体内
freopen("sample_data.in","r",stdin);
freopen("sample_data.out","w",stdout);
freopen("sample_data.in","r",stdin);
freopen("sample_data.out","w",stdout);
