In C programming, an enumeration type (also called enum) is a data type that consists of integral constants. To define enums, the enum keyword is used. enum flag {const1, const2, ..., constN}; By default, const1 is 0, const2 is 1 and so on. You can change default values of...

Predefined Functions So it turns out you already know what a function is. You have been using it the whole time while studying this tutorial! For example,main()is a function, which is used to execute code, andprintf()is a function; used to output/print text to the screen: ...

enumMyEnum{Banana,Apple,Pineapple,} 复制 但与C不同的是,MyEnum 是一个实数类型,而不仅仅是一个整数类型的别名。同样与C不同的是,枚举的变体不会被转储到全局命名空间,而是必须通过枚举类型来访问。MyEnum::Banana。请注意,与结构不同,枚举的变体是默认 pub 的。

Are "inline virtual" member functions ever actually "inlined"? 虚函数可以是内联函数,内联是可以修饰虚函数的,但是当虚函数表现多态性的时候不能内联。 内联是在编译器建议编译器内联,而虚函数的多态性在运行期,编译器无法知道运行期调用哪个代码,因此虚函数表现为多态性时(运行期)不可以内联。
APIs and Interfaces: Enums are useful while defining APIs or interfaces between different parts of a program. They provide a clear and structured way to communicate specific options or states between different modules or functions. Flags and Bitmask Operations: Enums can also be used with bitwise...
