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; 
}
