从C ++中的文本文件加载变量 [英] Loading Variables from Text File in C++

问题描述

我知道这个问题已被问过一百万次，但大多数问题比我需要的更复杂。我已经知道哪些行将有什么数据，所以我只想加载每行作为自己的变量。

I know this question has been asked a million times before, but most of the questions are more complex than I need. I already know which lines will have what data, so I just want to load each line as its own variable.

例如，在settings.txt：

For example, in "settings.txt":

800
600
32

然后，在代码中，第1行设置为int winwidth，第2行设置为int winheight，第3行设置为int wincolor。

And then, in the code, line 1 is set to int winwidth, line 2 is set to int winheight, and line 3 is set to int wincolor.

对不起，我对I / O很新。

Sorry, I'm pretty new to I/O.

推荐答案

你可以这样做：

std::ifstream settings("settings.txt");
int winwidth;
int winheight;
int wincolor;

settings >> winwidth;
settings >> winheight;
settings >> wincolor;

但是，这不会确保每个变量都在一个新行，并且不包含任何错误处理。

However this will not ensure that each variable is on a new line, and doesn't contain any error handling.
