C++获取系统时间

#include <iostream>

#include <ctime>

using namespace std;

void main()

{

tm *year; //年

tm *month; //月

tm *day; //日

tm *hour; //时

tm *minute;

tm *second;

t = time(0);

year = localtime(&t);

month = localtime(&t);

day = localtime(&t);

hour = localtime(&t);

minute = localtime(&t);

second = localtime(&t);

cout << (year->tm_year + 1900) << "年" //返回的是今年减1900,所以要加上1900

<< (month->tm_mon + 1) << "月" //因为Month (0 – 11; January = 0),所以要加1

<< day->tm_mday << "日"

<< hour->tm_hour << "时"

<< minute->tm_min << "分"

<< second->tm_sec << "秒"

<< endl;
