文件没有打开，即使它存在 [英] File is not opening even though it exists

问题描述

在下面的程序中，它成功地将数据写入 student.txt 文件，但是当我打开它并逐行打印文件时，它始终显示文件不找到了。

In the following program, it writes data successfully to student.txt file, but when I open it and print line by line of the file, it always shows file not found.

有人可以帮我吗？

    ifstream Myfile;


    Myfile.open("student.txt");


      if(!Myfile){
        cout<<"Sorry file can't be opened" <<endl;

        exit(1);
    }


        else
        { 

            // Use loop and read the names and ids from the file and display them 
        string line;
        while (getline(Myfile, line)){

        cout<<line<<endl;
    }

            // Close the file 
      Myfile.close();
