#include <iostream>
#include <string>
#include <vector>
using namespace std;

int main()
{
int num = 1;//计数
string word;//输入及记录单词
vector<string> vec;//储存文章

while (cin>>word && word[0] != '0')
{
vec.push_back(word);
}

vector<string>::iterator iter1 = vec.begin();
vector<string>::iterator iter2 = vec.begin();
word = *iter2++;

while(iter2 != vec.end())

else

++iter1;
++iter2;
}
if(fnum >= num)

word = *iter1;
num = fnum;
}
}
}
cout << word << "连续出现了" << num << "次" <<endl;
return 0;
}
--------------------VC++6.0编译-------------------------------------------------
输入:a a a b b b b a a a c c c c c b 0
打印:c连续出现了5次

为什么把
using namespace std;
换成
using std::string;
using std::vector;
using std::iterator;
using std::cin;
using std::cout;
using std::endl;
会出错
