QString str;char*ch;QByteArray ba=str.toLatin1();// mustch=ba.data(); 这样就完成了 QString 向 char * 的转化。经测试程序运行时不会出现 bug。注意第3行,一定要加上,不可以 str.toLatin1().data() 这样一步完成,否则可能会出错。 补充:以上方法当 QString 里不含中文时,没有问题,但是 QStr...

StrToVal (String To Value)将String转换成一个任意的其他变量。这个在和上位机通信过程中经常使用到类似的功能代码,具体的代码示例如下: PROC StringToVal() VAR string str15 := "[100, 200, 300]"; VAR bool ok; VAR pos posval; ok := StrToVal(str15,posval); TPWrite "Pos: "\Pos:=posval ...
JVM 维护了一个String Literal Pool,用来存储String Literal。 引用 A string literal consists of zero or more characters enclosed in double quotes. A string literal is a reference to an instance of class String. Moreover, a string literal always refers to the same instance of class String. 字符...
对于程序中的字符串临时变量,C++有一套特殊的处理方式,将其视为字符串字面量(string literal).字符串字面量实际上存储在内存的只读部分,也就是说,即使一个程序使用了500次"hello"字符串自变量,编译器也只在内存中创建一个hello实例.这种技术成为字面量池(literal pooling). ...
The String class provides methods for dealing with Unicode code points (i.e., characters), in addition to those for dealing with Unicode code units (i.e., char values). 除非另有说明,否则将null参数传递给String类中的构造函数或方法将引发NullPointerException。 String类采用UTF-16编码格式来表示一...
