Given a PIN (value in HEX) and bit number, we have to SET and then CLEAR given bit of the PIN (val) by using Macros. Macros definitions #define SET(PIN,N) (PIN |= (1<<N)) #define CLR(PIN,N) (PIN &= ~(1<<N))
C++11引入空指针主要用于定义模板类时和0的区别 operator:重载操作符or = || or_eq = |= reinterpret_cast转换 signed:代符号的intstatic静态声明可以放文件里表示文件范围内全局可见且编译的时候就已经分配内存空间,放函数里表示函数的一个状态只在第一运行时执行一次,放结构体里只是从属是所有结构体共用的不占结...
How to define getter and setter functions in JavaScript - GetterWhen a property is accessed, the value gets through calling a function implicitly. The get keyword is used in JavaScript. An identifier, either a number or a string is allowed for set.Setter
Here, we are going to learn how to define macros –In this example, we are defining two Macros YES and NO by using #define preprocessor directive.
预编译指令java预编译指令有哪些 C语言——预编译指令预编译关于编译参考关于宏定义 参考预编译又称为预处理,是做些代码文本的替换工作处理#开头的指令,比如拷贝#include包含的文件代码,#define宏定义的替换,条件编译等,就是为编译做的预备工作的阶段,主要处理#开始的预编译指令预编译指令指示了在程序正式编译前就由...

Moreover, the "var" keyword declared the variables and initialized using the equal(=) operator. Additionally, the declaration of multiple variables can happen like: var test1 = “John”, test2 = “Dheer”, test3 = 200; Accessibility of variables depends on whether they declare in the "local...
