在这个例子中,我们使用using MyPointer = T*语句定义了一个名为MyPointer的模板类型别名,从而可以使用MyPointer<int>来代替int*类型。 6、using enum 在C++11中,新增了using enum语法,用来为枚举类型定义别名,例如: #include <iostream> enum class Color { RED, GREEN, BLUE };
「Scoped and strongly typed enums」是 C++11 時所引進的一個新的功能,主要是要取代舊的列舉型別(enum)。 他的基本用法,是在 enum 後面,再加上 class 或struct;而要使用定義的值的時候,一定要加上範圍(scope、這邊就是 class 的名稱)。 下面就是簡單的比較: enum enum class enum EColor { RED, ...

usingstaticColor;enumColor { Red, Green, Blue }classProgram{publicstaticvoidMain(){ Color color = Green; } } 别名using 创建using别名指令,以便更易于将标识符限定为命名空间或类型。 在任何using指令中,都必须使用完全限定的命名空间或类型,而无需考虑它之前的using指令。using指令的声明中不能使用using别名...
如果你仍然希望保持匿名 `enum` 的风格，可以使用 `typedef` 来重命名它：```cpp class Graph { pub...
If we used the class-based approach above, we can loop through the keys of theSeasonclass to obtain all the enum values under the same group: Object.keys(Season).forEach(season=>console.log("season:", season))// season: Summer// season: Autumn// season: Winter// season: Spring ...

In some cases, the default mechanism for creating files from templates is insufficient. Consider a language that defines multiple types of core entities, e.g., in the Java language, the following entities can be created: Class, Interface, Record, Enum, and Annotation. ...
