Question

我正在尝试制作游戏的控制台版本“我收拾行李箱......”。基本的想法是我有一个.txt文件，里面有大约4.3k的随机名词，每行一个单词。我想读出这个文件中的单词并将它们放入vector<string>。接下来的步骤是让另一个向量包含玩家必须记住的单词等等。

但我现在很早就开始挣扎。几乎每次运行代码时都会发生的事情是它只是在“计算机始终启动”之后就停止了。玩得开心！打印到控制台。但是，我最后尝试了多个cout语句，我曾经得到一些值。但他们总是不同的。例如，当打印vector.size（）时，范围从0到4308（确切的行数）。在过去的30分钟里，该节目从未到过其中一个小组。

在linux mint下使用Clion 2016.1.1和CMake 3.5.1捆绑包
对file.txt的访问不受任何限制
file.txt的路径正确

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

#include "player.h"

using namespace std;

int main() {
    int player_score;
    string player_name;
    string line;
    vector <string> words_list;

    ifstream file;
    file.open("/home/rainbowterminal/ClionProjects/PackingBags/file.txt", ios_base::in);


    if(!file)
    {
        cerr << "Couldn't open file" << endl;
    }
    else

        while (getline(file, line))
        {
            words_list.push_back(line);
        }
    file.close();
    Player *player;
    player = new Player;

    cout << "Hey and welcome to 'I packed my suitcase and take with me'. You won't beat it. Promise." << endl;
    cout << "To start playing just enter your name" << endl;

    cin >> player_name;
    player->set_name(player_name);

    cout << "Okay " << player->get_name() << ", let's do this! You're a playing 'I packed my suitcase and take with me" << endl;
    cout << "against the computer. Just repeat the words printed to the console" << endl;
    cout << "and add an own word in the end. DO NOT seperate by commata. Letter case" << endl;
    cout << "doesn't matter. Computer always starts. Have fun! " << endl;



    //srand ((unsigned int) time(NULL));
    //int random = (int) (rand() % words_list.size());
    cout << words_list.size();
    cout << words_list[100];
    cout << player->get_name();
    //vector<string> used_words;
    //used_words.push_back(words_list[randomIndex]);



    return 0;
}

正如所建议我把它分解为基本问题。这段代码会发生什么？

cout << words_list.size();

仅在50％的trys中返回向量的大小。

int main() {
    string line;
    vector <string> words_list;

    ifstream file;
    file.open("/home/rainbowterminal/ClionProjects/PackingBags/file.txt", ios_base::in);

    if(!file) {
        cerr << "Couldn't open file" << endl;
    }
    else {

        while (getline(file, line)) {
            words_list.push_back(line);
        }
    }

    file.close();


    cout << words_list.size();


}

file.txt

如果有人能让我暗示我做错了什么，我会非常乐意自己解决这个问题。

为什么我的程序每次都有所不同？
