PAT乙级1002 部分正确是怎么回事

[y思无邪]

代码如下：
#include<iostream>
using namespace std;
int main() {
int n;
int sum = 0;
while ((n = getchar())!='\n')
sum += (n-'0') ;

int a[3]; int i = 0;

while (sum >= 10) {
a[i] = sum % 10;
i++;
sum /= 10;
}
if (sum < 10) a[i] = sum;

for (int j = i; j >= 0; j--) {
switch (a[j]) {
case 1:cout << "yi"; if (j != 0)cout << ' '; break;
case 2:cout << "er"; if (j != 0)cout << ' '; break;
case 3:cout << "san"; if (j != 0)cout << ' '; break;
case 4:cout << "si"; if (j != 0)cout << ' '; break;
case 5:cout << "wu"; if (j != 0)cout << ' '; break;
case 6:cout << "liu"; if (j != 0)cout << ' '; break;
case 7:cout << "qi"; if (j != 0)cout << ' '; break;
case 8:cout << "ba"; if (j != 0)cout << ' '; break;
case 9:cout << "jiu"; if (j != 0)cout << ' '; break;
}

}
return 0;
}

错误如下：

仔细看看题的要求 找不同

边界条件 输入输出格式 ……

来混分

[707wk]

#include<iostream>
using namespace std;

int main()
{
    char c;
    char putStr[][10] =
    {
        {"lin"},
        {"yi"},
        {"er"},
        {"san"},
        {"si"},
        {"wu"},
        {"liu"},
        {"qi"},
        {"ba"},
        {"jiu"}
    };
    for(; (c = getchar()) != '\n';)
    {
        cout << putStr[c - '0'] << " ";
    }
    return 0;
}

这样行不
