什么是C ++ 4.3.2中getdate（）函数的替代品？

Question

这在Turbo C ++中运行，但不适用于较新版本的C ++。有什么替代方案吗？

#include<stdio.h>
#include<dos.h>

main()
{
   struct date d;
   getdate(&d);
   printf("Current system date is %d/%d/%d\n",d.da_day,d.da_mon,d.da_year);
   return 0;
}

Answer 1

与getdate最直接的比喻是time + localtime

#include <stdio.h>
#include <time.h>       /* time_t, struct tm, time, localtime */

int main ()
{
    time_t rawtime;
    time ( &rawtime );

    tm * const ptm = localtime ( &rawtime );

    printf("Current system date is %d/%d/%d\n",
             ptm->tm_day,ptm->_mon+1,ptm->tm_year+1900);

    return 0;
}
