enum 枚举类型
🔗 [C enum(枚举) | 菜鸟教程] https://www.runoob.com/cprogramming/c-enum.html
// 程序来自https://www.runoob.com/cprogramming/c-enum.html
#include <stdio.h>
enum {
MON = 1, TUE, WED, THU, FRI, SAT, SUN
} day;
int main() {
for (day = MON; day <= SUN; day++) {
printf("%d\n", day);
}
}结果：
1
2
3
4
5
6
7

print("Enter/Paste your content. Ctrl-D or Ctrl-Z ( windows ) to save it.")
contents = []
while True:
try:
line = input()
except EOFError:
break
contents.append(line)
print(contents)OCR辅助查找工具
注意：第一个枚举成员的默认值为整型的 0，后续枚举成员的值在前一个成员上加1。我们在这个实例中把第一个枚举成员的值定义为 1，第二个 就为2，以此类推。可以在定义枚举类型时改变枚举元素的值：enum season {spring, summer=3, autumn, winter}；没有指定值的枚举元素，其值为前一元素加1。也就说 spring 的值为O，summer 的值为3， autumn 的值为4， winter 的值为5
