Rust也有一个专门的bool类型。它不能与整数隐式转换,否则就是一个u8,保证具有0x00或0x01的值,以及各自的字面意义false和true。bool支持所有的位操作,是唯一与短路的&&和||兼容的类型。它也是唯一可以在if和while条件下使用的类型。 整数有一套广泛的内置位操作,以方法的形式暴露出来,如x.count_zeros()和x.next...
The syntax for ado whilestatement is: doloop_body_statementwhile(cond_exp); where: loop_body_statementis any valid C statement or block. cond_expis an expression that is evaluated at the end of each pass through the loop. If the value of the expression is "false" (i.e., compares equ...

上文中提到foreach()是相对while()而言,在CMake中更加常用和简介的循环结构块,这个是因为foreach()在处理列表变量时十分便捷: 1、foreach(<loop_variable>IN[LISTS<lists>][ITEMS<items>]) CMake 将从所有提供的<lists> 列表变量中获取元素,也就是输入循环中的list可以是多个,然后再是从所有显式声明的<items...

语法分析(SyntaxAnalysis):根据词法分析的结果,将程序源代码转化为一个抽象语法树(AbstractSyntaxTree)。语义分析(SemanticAnalysis):对抽象语法树进行语义检查,确保程序的正确性。中间代码生成(IntermediateCodeGeneration):将抽象语法树转化为中间代码,通常是一种低级的表示形式。优化(Optimization):对中间代码进行优化,以...
