C++4.3.2 中 getdate() 函数的替代方法是什么?
Whats the alternative to the getdate() function in C++4.3.2?
这在 Turbo C++ 中运行,但不适用于较新版本的 C++。还有其他替代方案吗?
#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;
}
与getdate
最直接的类比是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;
}
或者,要获得更 "C++" 风格的方法,请查找 std::chrono
