We can also assign any integer value to any constant of enum.ExampleIn the following example, we are declaring an enum type and assigning different values to the enum constants.Open Compiler #include <stdio.h> enum status_codes { OKAY = 1, CANCEL = 0, ALERT = 2 }; int main() { /...
Allocate to an enum type only as many bytes as it needs for the declared range of possible values. Specifically, the enum type is equivalent to the smallest integer type that has enough room. Warning: the -fshort-enums switch causes GCC to generate code that is not binary compatible with ...
将Integer 转换为 Enum 将int转换为enum的基本思路是为每个枚举常量分配一个整数值,然后通过这个整数值查找对应的enum常量。我们可以通过定义静态方法来实现。 示例代码 假设我们有以下的枚举类型Day,其中每天都有一个对应的整数值: publicenumDay{SUNDAY(0),MONDAY(1),TUESDAY(2),WEDNESDAY(3),THURSDAY(4),FRIDAY(...
Integer>enumMap=newEnumMap<>(OrderStatus.class);for(OrderStatusstatus:OrderStatus.values()){enumMap.put(status,(int)(Math.random()*1000));// 随机赋值}longendTime=System.nanoTime(

To explicitly assign an integer value to a variable of an enumerated data type, use a type cast: 复制 workday = ( enum DAY ) ( day_value - 1 ); This cast is recommended in C but is not required. 复制 enum BOOLEAN /* Declares an enumeration data type called BOOLEAN */ { fals...
And, it defines the set of named integer identifiers (called the enumeration set, enumerator constants, enumerators, or members). A variable of the enumeration type stores one of the values of the enumeration set defined by that type. Variables of enum type can be used in indexing expressions...

A,值类型:内存顺序分配在栈中。他们包括:所有基本或内置类型(不包括string类型)、结构类型、枚举类型(enum type) B,引用类型:内存非线性分配在堆中,当它们不再被使用时CS通过垃圾收集器自动释放内存(C++用delete)。它们使用new运算符来创建。 引用类型包括:类类型、接口类型、象数组这样的集合类型类型、字串类型、...
typedef enum {..} AnEnum** Enum: AnEnum * If the C Caller takes an integer type, for example, int16_t, you can modify it to a fixed-point type with matching base type, for example to fixdt(1, 16, 3). ** The C Caller sync button prompts you to import struct or enum types ...
