问题描述：

如何将txt文件的每一行存储到一个单独的变量中，然后将它们打印到控制台屏幕？



我尝试过：



How do I store each line of a txt file into a separate variable then print them to the console screen?

What I have tried:

#include <iostream>
#include <fstream>
#include <sstream>
using namespace std;


int main()
{
    ifstream inputFile("C:/Users/jacob/OneDrive/Desktop/cpp/File List to Txt/Files.txt");
    string line;

    while (getline(inputFile,line))
    {

        istringstream ss(line);

        string name;
        string var1, var2, var3;

        ss >> name >> var1 >> var2 >> var3;
        cout <<name << endl << endl;
    }
}

答

读取每一行并打印它可以这样完成：



Reading each line and printing it can be done like so:

#include <iostream>
#include <fstream>
#include <sstream>
using namespace std;


int main()
{
    ifstream inputFile("C:/Users/jacob/OneDrive/Desktop/cpp/File List to Txt/Files.txt");
    string line;

    while (getline(inputFile,line))
    {
        cout << line << endl;
    }
}





将它存储在单独的变量中到底是什么意思？基于该描述，我建议将所有行读入数组。您的代码建议您尝试将单词拆分为单词？



What exactly do you mean with storing it in a separate variable? Based on that description I would suggest reading all the lines into an array. Your code suggests you're trying to split up the line in words though?
