TDateTime dt=Now();
TDateTime inc=TDateTime(1,0,0,0);
for(int i=0;i<20;i  )
    dt =inc;
 

引言: 我試著寫用for迴圈每次遞增一個小時時我用下列寫法

TDateTime dt=Now();
TDateTime inc=TDateTime(1,0,0,0);
for(int i=0;i<20;i  )
    dt =inc;
 

但是當我想每次遞增一個月或一年時應該要怎麼寫??

  int i;
  unsigned short Year, Month, Day;      TDateTime dt = Now();      dt.DecodeDate(&Year, &Month, &Day);      //加一個月
  for (i = 0; i < 20; i  )
  {
    Month  ;
    if(Month > 12)
      Year  ;        dt = EncodeDate((Word)Year, (Word)Month, (Word)Day);
  }      //加一年
  for (i = 0; i < 20; i  )
  {
    Year  ;        dt = EncodeDate((Word)Year, (Word)Month, (Word)Day);
  }

//加一個月
  for (i = 0; i < 20; i  )
  {
    Month  ;
    if(Month > 12)
    {         Month = 1;  //少了這一行
      Year  ;
    }        dt = EncodeDate((Word)Year, (Word)Month, (Word)Day);
  }
