正在从文件c++中读取数字

我想从文本文件中读取数字。该文件包含以下数字。

3 5 7 9 20 25 30 40 55 56 57 60 62 1 4 7 11 14 25 44 47 55 57 100 -5 100 1000 1005 -12 1000 1001

空格分隔数字。我不得不编写一些代码来阅读这篇文章，但问题是，读取行末的数字是不正确的，我不知道如何正确读取它们（CRLF字符的问题）；有人能帮我吗？这是我的密码。

收割台base.h

#include <iostream>
#include <fstream>
#include <string.h>
#include <cstdlib>
using namespace std;
class L
{
    public:
    int value;
};
class t
{
public:
    L *line;
    t(){
        line = new L[10000];
    }
};
class baza
{
public:
    ifstream in;
    ofstream out;
    string lines;
    char word1[1] ;
    int wordint;
    char tab[255];
    int *tab2;
    int x;
    int y;
    int z;
    int a;
    int b;
    int c;
    int ile;
    int multiplier;
    bool negative ;
    int negative;
    t *table;
    base();
};

这是base.cpp

    in.close();
