C++获取系统时间

标签：sizeof   内存   namespace   

//由于使用了windows.h，所以这种方法只能在windows系统下使用，不能在Mac或linux下使用

#include "iostream"
#include "windows.h"
#include "string"
using namespace std;

int main(){
	SYSTEMTIME ct;
	GetLocalTime(&ct);;//如果用GetSystemTime(&ct),则获取的是格林尼治时间

	int year = ct.wYear; 
	int month = ct.wMonth;
	int day = ct.wDay;
	int hour = ct.wHour;
	int minute = ct.wMinute;
	int second = ct.wSecond;
	
	cout << year << "/" << month << "/" << day << " "
		<< hour << ":" << minute << ":" << second << endl;

	//把时间转换成字符串
	char tmp[100];
	sprintf_s(tmp, "%d/%d/%d %d:%d:%d", year, month, day, hour, minute, second);

	string s = tmp;
	cout << s << endl;
	cout << tmp << endl;

	return 0;
}
