The system time is acquired by C + +

The Windows API, which contains the header file "Windows.h", is required to obtain system time in C/C + +.

The data type of the system time is SYSTEMTIME, and the following definitions can be queried in winbase.h:

typedef struct _systemtime {    WORD wyear;    WORD Wmonth;    WORD Wdayofweek;    WORD wday;    WORD Whour;    WORD Wminute;    WORD Wsecond;    WORD Wmilliseconds;} SYSTEMTIME, *psystemtime, *lpsystemtime;

It contains 8 messages, such as year, month, day, time, minute, second, millisecond, Day of the week (starting from Monday), all of which are word types.

In vc++6.0, Word is an unsigned short integer and is defined as follows:

typedef unsigned short      WORD;

There are two functions to get time: Getlocaltime () gets local time, GetSystemTime () gets Greenwich Mean time.

#include <iostream.h>#include "windows.h" int main () {    SYSTEMTIME ct;    Getlocaltime (&CT);//local time    //getsystemtime (&ct);//gmt time    cout<<ct.wyear<<  Endl;    cout<<ct.wmonth<<Endl;    cout<<ct.wday<<Endl;    cout<<ct.whour<<Endl; cout<<ct.wminute<<Endl; cout<<ct.wsecond<< Endl; cout<<ct.wmilliseconds<<Endl; Cout<<ct.wdayofweek<<endl;//day of a week, Start from Monday return 0;}
