检查自己的文件

Question

我正在尝试编写一个程序来检查其他单词中有多少单词。然后告诉用户哪个单词中有最多的单词。出于某种原因，while循环打破了，我无法重新加载文件。有任何想法吗？

#include <iostream> 
#include <string> 
#include <fstream> 

using namespace std; 

struct finalWord { 
    string word; 
    int number; 
}; 

ostream& operator<<(ostream& o, const finalWord& f) { 
    return o << f.word << ": " << f.number; 
} 

int main() { 

    finalWord f; 
    string line, holder, line2; 
    ifstream myFile("enable1.txt"); 
    int counter; 
    int holdlen; 
    size_t found; 
    if (myFile.is_open()){ 
     while(getline(myFile,line)){ 
      holder = line; 
      while (getline(myFile, line)){ 
       found = holder.find(line); 
       if (found != string::npos){ 
        counter++; 
       } 
       if (counter > holdlen) { 
        f.word = line; 
        f.number = counter; 
        holdlen = counter; 
       } 
       counter = 0; 

      } 

     } 
    } 

    cout << f << endl; 
}

其实你所面对的问题，是因为两个循环使用的是具有相同MYFILE

IN First WHILE loop it will take a word 

IN Second WHILE loop it will go through the rest of the file. 

这将在以下情况下的问题。

If a String "I am Happy" is occurred more than once then it will iterate for each occurrence to search up to end of the file. 

So to avoid that you need to take the unique strings in an vector as said by Vaughn Cato and then do a check for the occurrence of that string in the whole file to make it efficient.
