不是 Private 即私有变量是相对于对象来说的（只限于对象内部使用） 而C是面向过程的 不存在这个 有类似 不等效

事实几乎如此——二进制文件包含了 CPU 执行的所有代码,但代码分散在多个文件中,方式非常复杂。链接是一个简化事物并使机器代码整洁、易于消费的过程。 快速查看命令列表会让你知道 CMake 并没有提供很多与链接相关的命令。承认,target_link_libraries()是唯一一个实际配置这一步骤的命令。那么为什么要用一整章来讲述...

The recommended way to create concrete array types is by multiplying any ctypes data type with a positiveinteger. Alternatively, you can subclass this type and define _length_ and _type_ class variables. Array elementscan be read and written using standard subscript and slice accesses; for slice...
After applying these changes, public getter and setter functions for static (private) variables of the file will be generated, allowing access to these variables. In the scenario of test case SD_tc_0 a test action sets two static (private) variable...

主要点就两个:默认的访问级别和默认的继承级别 class都是private 28.派生类与虚函数概述 (1) 派生类继承的函数不能定义为虚函数。虚函数是希望派生类重新定义。如果派生类没有重新定义某个虚函数,则在调用的时候会使用基类中定义的版本。 (2)派生类中函数的声明必须与基类中定义的方式完全匹配。 (3) 基类中声...
