Question

我需要帮助我是新手。我的下面的文字是在一个单独的文件（football.txt）上创建的。我正在尝试创建一个程序，可以读取该数据并显示它。

Player name:    Rusell William
Salaray:        $8000000
Age:            20
Team:           Seahawks
Position:       Quarterback

这就是我所拥有的，

//This program will read the text files into display

#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
using namespace std;

int main()
{

//Declaring Variables

    int salary, age;
    string firstName, lastName, team, position;

//Delcaring a file.

    ifstream infile;
    infile.open("football.txt", ios::in);

    if (!infile)
{   cout<<"File does not exist";
}

    infile.close();

    ofstream outfile;

//Declare on display

    cout<<"**********Player Summary*********\n";
    outfile.open("football.txt", ios::app);
    outfile<<"football.txt";
    outfile.close();




return 0;
}

没有错误，但也没有显示。

试试这个示例程序并在其上构建：

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

using namespace std;

int main(void)
{
    ifstream infile;
    infile.open("football.txt", ios::in);

    if (!infile)
    {
       cout<<"File does not exist";
       return EXIT_FAILURE;
    }
    std::string text_from file;
    while (getline(infile, text_from_file))
    {
       cout << text_from_file << "\n";
    }

    cout << "Paused. Press enter to continue.\n"
    cin.ignore(10000, '\n');

    return EXIT_SUCCESS;
}

请注意，正在使用getline函数从文件中读取文本。
