C语言时间函数与枚举使用示例

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
enum weekday {Sun,Mon,Tue,Wed,Thu,Fri,Sat};
int main()
{
time_t rawtime;
struct tm *timeinfo;
enum weekday wday;

timeinfo =localtime(&rawtime); wday = (enum weekday) timeinfo->tm_wday; switch(wday) { case Mon: printf("交作业");break; case Tue: printf("打电话");break; case Thu: printf("watching MV");break; case Sat: printf("playing Ball");break; default: printf("Playing Game!s");break; } printf("Hello world!\n"); return 0;

}
