i have a structure
typedef struct tm
{
int date;
int hour;
int minutes;
} time;

i want to use this structure dynamically, ie, i want it to grow.

like it would be
time *sept= new time;
sept->date=15;
......
.........
.......
but i want something like

for(int i=0;i<MAX;i++)
{
sept[i]->date=i+5;
}

i want to grow the structure dynamically, ie, the valur of MAX is
provided at runtime.
how can i do tht????

Your names (tm and time) are both _very_ poorly chosen. The standard
library already defines both of these. OTOH, you might want to consider
using struct tm from the standard library -- it's a more comprehensive
version of what you have here.

It sounds to me like what you want isn't that the structure itself grow,
but that you have an expandable array of those structures.

You could do that with something like:

typedef struct my_time {
int date;
int hour;
int minutes;
} my_time;

std::vector<my_time> some_times(MAX);

The universe is a figment of its own imagination.

my actual structure is

typedef struct tagITEMINFO
{
DWORD dwFileAttributes;
CString strFileName;
DWORD nFileSizeLow;
FILETIME ftLastWriteTime;
} ITEMINFO;


BOOL CDataSync::AddItem(WIN32_FIND_DATA* pfd)
{ CListCtrl* pList = (CListCtrl*)GetDlgItem(IDC_LIST_CLIENT);
ITEMINFO* pItem;
pItem = new ITEMINFO;


//Initialize pItem from pfd
pItem->dwFileAttributes = pfd->dwFileAttributes;
pItem->strFileName = pfd->cFileName;
pItem->nFileSizeLow = pfd->nFileSizeLow;
pItem->ftLastWriteTime = pfd->ftLastWriteTime;
}




this is with one file, i want to save information about n number of
files. the function AddItem is called in some other function.
what i require is tht when i call AddItem, the attributes for one
object is stored in a buffer when when this function is called again,
the buffer adds another object and so on.
