回答by dshipper
You should just put a \nbetween heyand s. So:
你应该\n在hey和之间放一个s。所以：
string var = "hey\ns";

Line breaking can be achieved using Dan's advice:
可以使用 Dan 的建议实现换行：
string var = "hey\ns";
Note that you cannot do this the way you wanted:
请注意，您不能按照自己的方式执行此操作：
string var = "hey // this is not
s"; // valid code
and it's a design choice of C++.
它是 C++ 的设计选择。
Older languages generally do not allow you to define multiline strings.
较旧的语言通常不允许您定义多行字符串。
But, for example, Python does allow you exactly this:
但是，例如，Python 确实允许您这样做：
someString = """
this is a
multiline
string
"""
and printing someStringwill give you a true multiline string.
和打印someString会给你一个真正的多行字符串。
You can forget about this when using C++, though.
不过，在使用 C++ 时，您可以忘记这一点。

A line break is encoded as the char '\n'. So just write \ninto your string.
换行符被编码为 char '\n'。所以只需写入\n您的字符串。

You can also do this:
你也可以这样做：
string var =
"\
some text\n\
some more text\n\
and even more text\
";
and var would be equels to
和 var 将等于
some text
some more text
and even more text

you should try this string var = "hey"."/n"."s";
你应该试试这个字符串 var = "hey"."/n"."s";
