static member variable[可读可写] 可以通过指针间接修改变量的值 static const member variable[只读] 压根就不可以修改变量的值,会报错
~Simple(void); staticintGetInt(void); private: staticint_i; }; simple.cpp intSimple::GetInt(void) { return_i; } 连接出错: error LNK2001: unresolved external symbol "private: static int Simple::_i" (?_i@Simple@@0HA) 需要在.cpp文件中初始化静态成员变量,初始化跟所在位置无关 intSimple...
When a static member variable is declared private in a class, how can it be defined? In the very same way as you define a public static variable in your source(cpp) file. int static_demo::a = 1; Access specifiers will not give you error while defining the member. Access specifiers...

const datatype variablename = variablevalue ; 为什么const能很好地取代预定义语句? const 到底有什么大神通,使它可以振臂一挥取代预定义语句呢? 1. 首先,以const 修饰的常量值,具有不可变性,这是它能取代预定义语句的基础。 2. 第二,很明显,它也同样可以避免意义模糊的数字出现,同样可以很方便地进行参数的调整...
