1定义一个CTime类对象 CTime time; 2得到当前时间 time = CTime::GetCurrentTime(); 3 GetYear(),GetMonth(), GetDay(), GetHour(), GetMinute(), GetSecond(), GetDayOfWeek() 返回整型（int）对应项目 4 将当前时间格式化 CString date = time.Format("%Y-%m-%d %H:%M:%S %W-%A"); 说明： 1) 结果为：2006-10-13 17:23:47 41-Friday 2) 格式符号说明 %a—— 星期（缩写英文），如Fri； %A—— 星期（全写英文），如Friday %b—— 月份（缩写英文），如Oct %B—— 月份（全写英文），如 October %c—— 月/日/年时:分:秒，如 10/13/06 19:17:17 %m—— 月份（数字 1 ~ 12） %d—— 日期（1 ~ 31） %H—— 时（24小时制）（0 ~ 23） %I—— 时（12小时制）（0 ~ 12） %M—— 分（0 ~ 59） %p—— 12小时中的AM/PM指示，或者AM，或者PM %S—— 秒（0 ~ 59） %j—— 一年当中的第几天，（1 ~ 366） %U—— 一年中的第几周，星期日作为每周的第一天（0 ~ 53）

面试官：如果 http 响应头中 ETag 值改变了，是否意味着文件内容一定已经更改

阅读更多关于面试官：如果 http 响应头中 ETag 值改变了，是否意味着文件内容一定已经更改

本篇文章由我的一日一题中的四个 Issue 组合而成【Q111】http 响应头中的 ETag 值是如何生成的【Q112】如果 http 响应头中 ETag 值改变了，是否意味着文件内容一定已经更改【Q115】文件系统中 mtime 和 ctime 指什么，都有什么不同【Q116】http 服务中静态文件的 Last-Modified 是根据什么生成的不一定，由服务器中 ETag 的生成算法决定。详见 #112 比如 nginx 中的 etag 由 last_modified 与 content_length 组成，而 last_modified 又由 mtime 组成当编辑文件却未更改文件内容时， mtime 也会改变，此时 etag 改变，但是文件内容没有更改。 http 服务中静态文件的 Last-Modified 根据什么生成比奇小说网 m.biqi.org 一般会选文件的 mtime ，表示文件内容的修改时间 nginx 也是这样处理的，源码见: ngx_http_static_module.c r->headers_out.status = NGX_HTTP_OK; r->headers_out.content_length_n = of.size; r->headers_out.last_modified_time = of.mtime;

问题 This question already has answers here : How to print function pointers with cout? (7 answers) Closed last year . A couple of developers and I were wondering why: std::cout<<std::time<<std::endl; prints out a value of 1. What does the value represents, and why the value is of 1. Answer to what happened: How to print function pointers with cout? The C++ Standard specifies: 4.12 Boolean conversions 1 An rvalue of arithmetic, enumeration, pointer, or pointer to member type can be converted to an

问题 Preface: I've been learning C this past summer and only recently started learning C++ so I don't know very much of it yet. I've been trying to write a C/C++ program that recognizes right and left mouse clicks in windows and saves which button was clicked and when into an array of pointers to strings char **clicks . I'm organizing it as a sequence like: button, time, button, time... Whenever a mouseclick is detected, it takes either "R" or "L" and does this: void writeClick(char *button) {

问题 I am trying to get the running time of Insertion Sort Algorithm. MSDN said that using CTime could get the Elapsed Time. But I tried many times and always got zero. I thought it is impossible that the time of running this algorithm is zero. There must be some error or something else. Could anybody help me? I posted my code below: #include <cstdlib> #include <iostream> #include <atltime.h> using namespace std; //member function void insertion_sort(int arr[], int length); int *create_array(int

问题 I am having to deal with some time conversions in my application. I would like to stick to using standard library functions as much as possible. Right now I am using a time_t structure as my system time base. However, some devices can sync time to my device, and that time may or may not be UTC. Also, my device will sync time to another device and that time WILL always be UTC. Anyway, I can ask the user what the time zone is of the time that is being synced to my device and whether or not they

问题 I am timing how long it takes to do three different types of searches, sequential, recursive binary, and iterative binary. I have those in place, and it does iterate through and finish the search. My problem is that when I time them all, I get 0 for all of them every time, even if I make an array of 100,000, and I have it search for something not in the array. If I set a break point in the search it obviously makes the time longer, and it gives me a reasonable time that I can work with. But
