用STL 中的 Map 写的

 #include <iostream>
 #include <cstdio>
 #include <cstdlib>
 #include <cstring>
 #include <string>
 #include <map>
 using namespace std;

 map<string, int> ballon;
 string tmp;

 int main()
 {
     int i, j, n;
     while (cin >> n && n)
     {
         ballon.clear();
         for (i = ; i < n; i++)
         {
             cin >> tmp;
             ballon[tmp]++;
         }
         map<string, int>::iterator iter, poi;
         int maxp = ;
         for (iter = ballon.begin(); iter != ballon.end(); iter++)
         {
             if (maxp < iter->second)
             {
                 maxp = iter->second;
                 poi = iter;
             }
         //    cout << iter->first << "  " << iter->second << endl;
         }
         cout << poi->first << endl;
     }
     return ;
