将|| 视为字符串连接操作符 (+)(同 CONCAT()),而不视为 OR。 ANSI_QUOTES 将" 视为识别符,如果启用 ANSI_QUOTES,只有单引号内的会被认为是 String Literals,双引号被解释为识别符,因此不能用双引号来引用字符串。 IGNORE_SPACE 若开启该模式,系统忽略空格。例如:“user”和“user ”是相同的。

StringBuilder: Use StringBuilder when you are concatenating an arbitrary number of strings, such as in a loop or ...

前言 在汽车工业、航空航天、医疗设备等高安全性和高可靠性要求的嵌入式系统领域,软件的质量至关重要。代码中的细微缺陷都可能导致严重的后果。为了解决嵌入式 C 语言开发中常见的安全性和可靠性问题,汽车产业软件可靠性协会 (MISRA) 发布了 MISRA C 编码标准。 1. MISRA
Unlike string literals, string objects created with the new keyword are not automatically interned or stored in the string pool. String objects are mutable, meaning you can change their values using methods such as concat(), substring(), or replace().String object1 = new String("Hello"); St...
