'\\\<br/>'或“\\\<br/>”之间的区别是什么？在C ++？ [英] What is the difference between '\n' or "\n" in C++?
问题描述
我看到一个新行 \\\在一些代码示例中使用了2种不同的方式。第一个是
'\\\，第二个是
'\\\。有什么区别，为什么你会使用'\\\？
'
I've seen the new line \n used 2 different ways in a few code examples I've been looking at. The first one being '\n' and the second being "\n". What is the difference and why would you use the '\n'?
$ c>'\\\
'表示一个字符，\\\表示一个字符串，但是这么做吗？
I understand the '\n' represents a char and "\n" represents a string but does this matter?
推荐答案
'\\\是一个字符常数。
'
\\\是等同于 {'\\\（
'，'\ 0'} \\\加上空终止符）
"\n" is a pointer to character array equivalent to {'\n', '\0'} (\n plus the null terminator)
EDIT
我意识到我解释了这个差异，但没有回答这个问题。
I realize i explained the difference, but didn't answer the question.
您使用哪一个取决于上下文。如果你正在调用一个需要一个字符的函数，并且\\\，则使用'\\\
'
Which one you use depends on the context. You use '\n' if you are calling a function that expects a character, and "\n", if it expects a string.
