问题描述

我是编程的初学者，我正在尝试编写一个代码，从文件中读取 2 个数字，然后将其显示在 turbo c++ 的输出窗口中.我的代码只读取第一个数字并为第二个数字产生错误的输出.

I am a beginner in programming and I am trying to make a code that reads 2 numbers from a file and then displays it in the output window on turbo c++. My code only reads the first number and produces incorrect output for the second number.

 #include<iostream.h>
 #include<fstream.h>
 #include<conio.h>

void main()
{
    int x, y;
    clrscr();
    ifstream inFile;
    ofstream outFile;
    inFile.open("prac.txt");

    while(!inFile.eof())
    inFile >> x >> y;
    cout << x << " " << y;

    inFile.close();

}
