明确指定任何或所有枚举数的整数值

以下是如何定义 Weekday 类型以使枚举器值从1开始：星期一到星期日的数字值将对应于值1到7。

#include <stdio.h> 
int main(voID) { 
  enum Weekday {Monday = 1, Tuesday, Wednesday, Thursday, FrIDay, Saturday, Sunday};  

  enum Weekday today = Wednesday;
  printf("Weekday created\n");

  printf("%d\n",today);

  return 0; 
}
