Question

#include <iostream>
#include <fstream>
#include <map>
#include <set>
#include <string>
using namespace std;

int main(int argc, const char *argv[]) {
  ifstream inflie(argv[1]);
  int currentLine = 1;
  vector<string> words;
  map<vector<string>, int> freq;
  string line;
  while (getline(infile, line)) {
    istringstream inputString(line);
    currentLine++
    string word;
    while(inputString >> word){
      words.push_back(pair(word, currentLine));
      freq[words]++;
  }
  map<vector<string>, int>::const_iterator iter;
  for (iter=freq.begin(); iter != freq.end(); ++iter) {
    cout << iter->second << " " << iter->first << endl;
  }
  return 0;
}

这是我到目前为止所拥有的。当我尝试编译时，它给了我多个错误。请记住，我做的最后一个c ++的东西是在大约两年前的高中。我真的完全不知道自己在做什么。

这是我的错误（这真的很难过）：

C ++程序输出L：N形式的对列表，其中L是行号，N是给定单词的出现次数
