时间函数

[tracy07056]

取计算机当前时间的函数怎么写啊,要求能在主函数里调用这个时间值

[mo229mo]

#include <iostream>
#include <time.h>
using namespace std;

class CGetTime
{
time_t m_timenow;
struct tm *m_pLocatime;
char *m_strTime;
public:
CGetTime();
void Display();

};

CGetTime::CGetTime()
{
time(&m_timenow);
m_pLocatime=localtime(&m_timenow);
m_strTime=asctime(m_pLocatime);
}
void CGetTime::Display()
{
cout<<m_strTime;
}
int main()
{
CGetTime myTime;
cout<<"Now Time is: "<<endl;
myTime.Display();

}

C标准库函数localtime();

#include <stdio.h>
using namespace std;
#include <time.h>
int main(void)
{
time_t t = time(0);
char tmp[64];
strftime( tmp, sizeof(tmp), "%Y/%m/%d %X %A 本年第%j天 %z",localtime(&t) );
puts( tmp );
return 0;
}//main()
