C++ 特殊字符


字符串 - 特殊字符

由于字符串必须写在引号内,C++ 会误解此字符串,并生成错误

string txt = "We are the so-called "Vikings" from the north.";

解决此问题的办法是使用 **反斜杠转义字符**。

反斜杠 (\) 转义字符将特殊字符转换为字符串字符

转义字符 结果 描述
\' ' 单引号
\" " 双引号
\\ \ 反斜杠

序列 \" 在字符串中插入双引号

例子

string txt = "We are the so-called \"Vikings\" from the north.";
试试看 »

序列 \' 在字符串中插入单引号

例子

string txt = "It\'s alright.";
试试看 »

序列 \\ 在字符串中插入单个反斜杠

例子

string txt = "The character \\ is called backslash.";
试试看 »
