编译器控制语句允许程序改变编译器的行为,包含编译配置语句和行控制语句。 控制流语句则用于控制程序执行的流程,Swift 中有多种类型的控制流语句:循环语句、分支语句和控制转移语句。循环语句用于重复执行代码块;分支语句用于执行满足特定条件的代码块;控制转移语句则用于改变代码的执行顺序。另外,Swift 提供了 do 语句,用于构建局部作用域,还

swiftcode 有纯数字吗 参考Swift 官方教程《The Swift Programming Language》中文版 高级运算符 除了基本操作符中所讲的运算符,Swift还有许多复杂的高级运算符,包括了C语言和Objective-C中的位运算符和移位运算。 不同于C语言中的数值计算,Swift的数值计算默认是不可溢出的。溢出行为会被捕获并报告为错误。你是故意...
运算符是检查, 改变, 合并值的特殊符号或短语. 例如, 加号 + 把计算两个数的和(如 let i = 1 + 2). 复杂些的运行算包括逻辑与&&(如 if enteredDoorCode && passedRetinaScan), 还有自增运算符 ++i 这样让自身加一的便捷运算. Swift支持大部分标准C语言的运算符, 且改进许多特性来减少常规编码错误. 如...
