解析 C++ 中由制表符和换行符分隔的字符串；

Question

我正在为一个个人项目编写一个程序，该项目想要从谷歌图书中获取单词列表及其出现次数，并将它们放入一个带有其出现次数的向量中，以便我可以将列表削减一些。单词列表的格式如下：包含单词、\t 字符、数字、换行符 (\n) 和重复项。我对这种类型的编程没有太多经验，我想知道有人如何解析以这种方式格式化的文件。这是我到目前为止所拥有的：

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

#define FILE_NAME

using namespace std;

// structure denoting a word occurence
// contains the string of the word and an integer representing its frequency
struct word_occ {
    String word;
    int occurence;
};

vector<word_occ> words_vector;


int main() {
    /*
    File is a .txt file that has the following format:
    word1  #####
    word2  #####

    where word is the word from the english 1-grams from google books
    and ##### is the number of occurences.
    The word is separated from it's occurences by a tab (\t) and other words by a newline (\n).
    All words are entirely lowercase, and all numbers are integers lower than 20,000,000
    */
    ifstream all_words_list(FILE_NAME);
    
    string line;

    string line_word;
    int line_occurence;

    word_occ this_line;

    while (getline(all_words_list, line)) {

        // ... <-- what goes here?

        this_line.word = line_word;
        this_line.occurence = line_occurence;
        words_vector.push_back(this_line);
    }
}

字符串流可能会起作用：

while (getline(all_words_list, line)) {
    std::istringstream ss(line);
    ss >> line_word;
    ss >> line_occurence; 

    ...
