<errno.h>定义了一个int类型的表达式errno,可以看作一个变量,其初始值为0,一些标准库函数执行中出错时将它设为非0值,但任何标准库函数都设置它为0。 <errno.h>里还定义了两个宏EDOM和ERANGE,都是非0的整数值。数学函数执行中遇到参数错误,就会将errno置为EDOM,如出现值域错误就会将errno置为ERANGE。 三、输...

5. range ⼀一. 列列表 1.1 列列表的介绍 列列表是python的基础数据类型之⼀一 ,其他编程语⾔言也有类似的数据类型. 比如JS中的数 组, java中的数组等等. 它是以[ ]括起来, 每个元素⽤用' , '隔开⽽而且可以存放各种数据类型:
, value.GetType().Name, value, result.GetType().Name, result); } catch (OverflowException) { Console.WriteLine("{0} is outside the range of the Int16 type.", value); } } // The example displays the following output: // -3.4028235E+38 is outside the range of the Int16 type. ...
