hdu 2629 Identity Card string类用于c的字符串函数上

    这几天做ACM Step，比较不错，在做一道题的时候，我用的是string，函数用的是strncmp，说参数不匹配，看了看函数原型，参数是const char *，而我用的是string，需要转换一下：

 #include<iostream>

using namespace std;
int main()
{
    int n,i,temp;
    char s[50];
    string regional[8]={"Zhejiang","Beijing","Taiwan","Hong Kong","Macao","Tibet","Liaoning","Shanghai"};
    string id[8] = {"33", "11", "71", "81", "82", "54", "21", "31"};
    cin>>n;

                 while(n--)
                 {
                           cin>>s;
                           cout<<"He/She is from ";
                           for(i=0;i<8;i++)
                           {
                                            if (strncmp(s, id[i].c_str(), 2) == 0)
                                           {
                                                            cout<<regional[i];
                                                            break;
                                           }
                           }


                     cout<<",and his/her birthday is on "<<s[10]<<s[11]<<","<<s[12]<<s[13]<<","<<s[6]<<s[7]<<s[8]<<s[9]<<" based on the table."<<endl;

             }

}
