Hi all,
I need to know, what is the difference between dynamic memory
allocation, and stack allocation ?
1. If I have a class named DestinationAddress, when should I use
dynamic memory allocation to create object of that class ?
2. If it says "dynamic memory allocation", is it mean the
following code :
DestinationAddress* dest = new DestinationAddress(); // code 1

I'm trying to dynamically allocate memory to an array of strings
with the following (incomplete, for reference only) :
int nLines, nChars, m, n, Cols.sTcolumn ;
char ***sAtt;
sAtt = (char ***)malloc(nLines * sizeof(char *));
for(m=0; m < nLines; m++)

In C programming, I want to know in what situations we should use
static memory allocation instead of dynamic memory allocation. My
understanding is that static memory allocation like using array is
faster than malloc, but dynamic memory allocation is more flexible.
Please comment... thanks.

Hello all,
I have a question about loading DB2. I ran a DSN1COPY against a
imagecopy of 1 tablespace and the output to a flat file instead of the
original DB2 VSAM dataset. Can I use this flat file to load a DB2
table that was dropped and recreated? In this shop, not everyone has
authority to work directly with the underlying DB2 VSAM datasets for
security reasons.
How can one find out from a imagecopy the OBID of the table in that

i have some doubts on dynamic memory allocation and stacks and heaps
where is the dynamic memory allocation used?
in function calls there are some counters like "i" in the below
function. Is this stored in stack. If yes whether it will be deleted
on exiting from the function.
is dynamic memory allocation needed for this purpose

I have created a program to print the input words on stdout. Input is
taken dynamically from stdin. In each word, each input character is
allocated dynamically. I have ran this program with a file containing a
*single* word made of 25525500 letters and this program works fine on it.
I will welcome any suggestions for improvement.

Hi,
My database has only one table which is segmented and has wround 20 M rows. This tablespace has 2 VSAM datasets A001 and A002 at the source and also in the target.
I am using the image copy to refresh target environment using DSN1COPY.
The below error says of OBID 16 which is not the right identifier for the tablespace from the catalog or from DSN1PRNT.
So I am sure that sysxlat input is 100% right.
As I want the same data of...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
