如何包含字符串标题？ [英] How do I include the string header?

问题描述

我正在尝试了解 string s，但是不同的资料告诉我包括不同的标头。

I'm trying to learn about strings, but different sources tell my to include different headers.

有人说使用< string.h> ，但其他人提到 apstring.h 。我可以使用 apstring 做一些基本的事情，但有人告诉我另一个更强大。当我包含< string.h> 并尝试声明一些字符串变量时，出现错误。正确的用法是什么？

Some say to use <string.h>, but others mention "apstring.h". I was able to do some basic stuff with apstring, but I've been told the other one is more powerful. When I include <string.h> and try to declare some string variables, however, I get errors. What is the proper usage?

推荐答案

您要包含< string> 并使用 std :: string ：

#include <string>
#include <iostream>

int main()
{
    std::string s = "a string";
    std::cout << s << std::endl;
}

但是您真正需要做的是获取入门级书籍。您不会以其他任何方式正确学习，当然也不会在网上获取信息。

But what you really need to do is get an introductory level book. You aren't going to learn properly any other way, certainly not scrapping for information online.
