推荐答案
是创建一个ofstream类的实例,并使用它来写入你的文件。这里有一个指向一个网站的链接,其中包含一些示例代码,以及一些有关C ++大多数实现的标准工具的更多信息:
One way to do this is to create an instance of the ofstream class, and use it to write to your file. Here's a link to a website that has some example code, and some more information about the standard tools available with most implementations of C++:
为了完整起见,以下是一些示例代码:
For completeness, here's some example code:
// using ofstream constructors.
#include <iostream>
#include <fstream>
std::ofstream outfile ("test.txt");
outfile << "my text here!" << std::endl;
outfile.close();
您要使用std :: endl结束行。另一种方法是使用\\\
字符。这两个东西是不同的,std :: endl刷新缓冲区并立即写入你的输出,而'\\\
'允许outfile把你的所有输出到一个缓冲区,也许以后写。
You want to use std::endl to end your lines. An alternative is using '\n' character. These two things are different, std::endl flushes the buffer and writes your output immediately while '\n' allows the outfile to put all of your output into a buffer and maybe write it later.
