一 时间操作

    time_t tt;
    time(&tt);

    tm *time = localtime(&tt);
    char* ws[] = {
        "星期日",
        "星期一",
        "星期二",
        "星期三",
        "星期四",
        "星期五",
        "星期六",
    };

    printf("%d/%d/%d (%s) %02d:%02d:%02d\n",
        time->tm_year + 1900, time->tm_mon + 1, time->tm_mday, ws[time->tm_wday],
        time->tm_hour, time->tm_min, time->tm_sec);
}
/*

*/

 

int main(int argc, char *argv[], char **envp)
{
    time_t tt;//long __int64
              //printf("请输入你的生日：（年月日时分秒）");
    time_t t1 = time(NULL);
    tm time = { 35,11,9,31,11,2015 - 1900 };
    tt = mktime(&time);
    printf("%d", tt);

    return 0;
