Yes.
When allocating memory, there is *always* the possibility that the allocation will fail
and you will get a NULL pointer back. So assume that this is always possible.
APpending data to a string is a very expensive operation. Given you know the maximum size
of the string, this is a place where you might want to pre-allocate a buffer of 3MB and
just fill it. Whether or not you later convert it to a CString is yet a different
question.

In one of the scenario, i need to keep on appending data to a string. TheJoseph M. Newcomer [MVP]
final data size will be of 3 MB, (i.e) the string had to hold data of 3 MB,
the string had to be in memory util 3MB data is getting filled up
Will there be any risk or any crash happening?
