C ++ ofstream文本对话问题。 [英] C++ ofstream text aligment problem.

问题描述

我对齐文字时遇到问题：

I have problem aligning text:

Student Name           Test Score  Grade
Donald, Duckey               85      B
Goofy, Goof                  89      B
Balto, Brave                 93      A
Smitn, Snow                  93      A
Wonderful, Alice             89      B

我是使用< iomanip> setw的标题和对齐左的功能，但我只能做到这样的事情：

I am using the <iomanip> header for the "setw" and align "left" functions but I only manged to achieve something like this:

Student Name           Test Score  Grade
Donald   ,Duckey            85        B
Goofy    ,Goof              89        B
Balto    ,Brave             93        A
Smitn    ,Snow              93        A
Wonderful,Alice             89        B

这是我的代码：

Here is my code:

outFile << left << setw(9)
<< student[i].studentLName << ","
<< left << setw(10) << student[i].studentFName
<< right << setw(10) << student[i].testScore << setw(9)
<< student[i].grade << endl;

有没有人知道如何修复它？或者可能是不同的方法？

Does anyone have an idea on how to fix it? Or maybe different approach?

推荐答案

我会通过连接名字，逗号，姓氏来建立完整的名称。然后你可以将它作为一个具有预定宽度的项目写入文本文件，逗号将出现在正确的位置。

I would build the complete name by concattenating first-name, comma, last-name. Then you can write this to the text file as one item with predetermined width and the comma will appear at the correct place.
