The logical operators have lower precedence than the individual comparison operators, which makes sense because the comparison has to be evaluated before the logical operator can be evaluated.
逻辑运算符的优先级低于单独的比较运算符,这一点意义重大,因为必须先计算比较运算符,然后才能计算逻辑运算符。
The operators work by comparing each individual element of the two participating tuples from left to right (see Listing 6).
这些运算符的工作原理是从左到右地比较两个参与元组的每个单独的元素(请参见清单6)。
A scanner reads in the individual characters of a buffer and returns symbols (called tokens) that the parser will understand — such as keywords, operators, and language-specific punctuation.
扫描程序读取缓冲中的单个字符并返回解析器能理解的记号(称做标记)——如关键字、操作符及针对特定语言的标点符号。
