标准：：超出矢量<string>范围

我知道这个问题太老了，但是我找不到任何解决方法。

这是我的代码:

#include "string"
#include "vector"
#include "conio.h"
#include "fstream"
using namespace std;
using std::vector;
#define Ifile "Input.txt"
#define Ofile "Output.txt"
#define token1 "."
#define token2 "!"
#define token3 "?"

I got problem in

void Import(vector<string> &source)
{
        fstream file;
        char* fin = "Input.txt";
        file.open(fin,ios::in||ios::out);
        while(!file.eof())
        {
                getline(file,source.at(0));
        }
        SplitParagraph(source,token1);
        SplitParagraph(source,token2);
        SplitParagraph(source,token3);
        file.close();
}

当我跑到

getline(file,source.at(0));

编译器说:未处理的异常在0x758E1D4D在02.exe: Microsoft c++ exception: std::out_of_range在内存位置0x003FF4D8.

然后使用std::string

void Import(vector<string> &source)
{
        fstream file;
        char* fin = "Input.txt";
        file.open(fin,ios::in||ios::out);
        std:string STRING;
        while(!file.eof())
        {
                getline(file,STRING);
        }
        SplitParagraph(source,token1);
        SplitParagraph(source,token2);
        SplitParagraph(source,token3);
        file.close();
}

但是我不知道如何复制"STRING"到"source"

我试着搜索但没有找到。

如何修复out_of_range错误或将"STRING"复制到"source"

我所需要的就是解决这个问题。

谢谢!
