C++primer习题6.12找出重复单词

看了答案之后，我表示我考虑多了，写复杂了，但是还是贴出来吧：

the code in c++ primer ：

#include <iostream>
#include<vector>
#include<string>

using namespace std;

int main()
{
  string preword, currword,repword;
  int currCnt = 0, maxCnt =1;
  while (cin >> currword)
  {
      if (currword == preword)
      {
          ++currCnt;
      }
      else
      {
          if (currCnt > maxCnt)
          {
              maxCnt = currCnt;
              repword =preword;
            
          }
          currCnt = 1;
      }
      preword = currword;
  }
  if (maxCnt != 1)
  {
      cout << repword << " " << maxCnt <<endl;
  } 
  else
  {
      cout << "no repeated word." << endl;
  }
}

mine ：

#include <iostream>
#include<vector>
#include<string>

using namespace std;
struct note
{
	int local;
	int re_num;
};
int main()
{
	vector<string> stc;
	string s; 
	cout << "Please input the strings gapping with balck space and end with 'ctrl+A' "<<endl;
	while(cin >> s)
		stc.push_back(s);
	int j = 0 , num = 0, size = stc.size();
	vector<note> ivec;
	for(size_t i = 0; i != size-1; ++i)
	{
		num = 1;
	    j = i+1;
		while(j != size-1 && stc[i] == stc[j++])
		{
			++num;
		}
		if (num != 0)
		{
			note a = {i,num};
			ivec.push_back(a);
		}
	}
	note re_max = ivec[0];
	for (size_t i = 1; i < ivec.size(); ++i)
	{
       if (re_max.re_num < ivec[i].re_num)
       {
		   re_max = ivec[i];
       }
	}
	cout << "The word : " << stc[re_max.local] << " repeat " << re_max.re_num << " times" << endl;
}
