staticSystem.Mathclass contains methods that perform mathematical operations, without any requirement to store or retrieve data that is unique to a particular instance of theMathclass. That is, you apply the members of the class by specifying the class name and the method name,...
__inline void wr_cmd (unsigned char c) 中的_inline呢? 答案 __IO 一般宏定义为volatile,表示可读可写volatile 就是为了禁止编译器对其优化,因为对于timingdelay来说 你要设置一个初始值 但是变化是在中断中进行的 编译器不知道 会吧这个变量优化掉,inline表示内联函数,有...相关推荐 1static __IO uint32...
1.Static int data语句说明data为类变量，为一个类的共享变量，是所有对象共享的，它不 属于任何对象，是属于整个类的（静态方法也是一样）。2.Static定义的是一块为整个类共有的一块存储区域。3.其变量可以通过类名去访问：类名.变量名（与通过对象引用访问变量是等价的）。2）静态方法（修饰方法）...

When you build on the Visual Studio command line, you must build the program in two steps. First, runcl /c /EHsc MathLibrary.cppto compile the code and create an object file that's namedMathLibrary.obj. (Theclcommand invokes the compiler, Cl.exe, and the/coption specifies compile withou...
type MyUnion = | { status: "success"; data: string } | { status: "failed"; error: Error }; Such unions can be represented with the z.discriminatedUnion method. This enables faster evaluation, because Zod can check the discriminator key (status in the example above) to determine which ...
