Hi all:
When I run my code, I find that the memory that the code uses keeps
increasing.
I have a PC with 2G RAM running Debian linux. The code consumes 1.5G
memory by the time it finishes execution. But I do not think it needs
so much memory. About 500M memory should be enough. I have following
questions about memory leak.
(1).If in my code I only define constructor for my class, and do not
define destructor, will it cause memory leak?

Hello,
I am trying to debug some complex debug code.
In order to track the use of dynamically allocated memory,
I replaced the standard global new and delete operators.
(Not for changing the memory allocation algorithm, but
for gathering some statistics and to find memory leaks.)
This seems to work.
However, I noticed that my replacing delete operator is not called

Hi,
I'm 99 % sure that Standard C guarantees to do a memory move inside
realloc() in case the new, returned memory block (address) is different than
the original one. Can any C expert confirm this to me, please?
Thanks,
Jonas
PS. I using C90, not C99--if it makes a difference.

i have series of questions
1.How a c program is loaded in memory
i mean the whats is the structure that the code segment?? data segment??
2.When you say
const int *p;
where is p stored in the memory?? what happens internal so that its a read only.
3. when declared
volatile int *p
where exactly in the memory it is stored.

Hello,
This is a simple question for you all, I guess .
int main(){
double *g= new double;
*g = 9;
delete g;
cout<< sizeof(g)<<" "<<sizeof(double)<<" "<<sizeof(*g)<<" "<<*g<<" "<<endl;
*g = 111;
cout<< sizeof(g)<<" "<<sizeof(double)<<" "<<sizeof(*g)<<" "<<*g<<" "<<endl;

I finally narrowed down my code to this situation, quite a few (not all) of
my CMyClass objects got hold up after each run of this function via the
simple webpage that shows NumberEd editbox. My memory profile shows that
those instances survive 3 rounds of GC collections - it's not what I
expected. In my real code, CMyClass occupies big amount of memory and they
all share one stance of another class that I don't have enough memory hold...

hi all,
I have been doing some performance testing of a asp_net website, to be
hosted on a shared server ..
as far as i understand every page when accessed first time is compiled
and loaded in the memory of aspnet_wp , so that would mean more distinct
pages more the memory consumed by aspnet_wp, this is good since it would
mean serving compiled copy of the page , which is good for speed..
another understanding is that once a page is...

I have a STL vector of of characters and the character class has a

The things are vector<Characterchars; and

Now are the memory layout is contiguous? i.e all the character resides
side by side just like array, and all Points side by side insede the

Hi All,
I need to know the memory required by a c program. Is there any
tool/utility which can give me the memory usage in terms of DATA
segment, TEXT segment, BSS segment etc.
I am working on linux platform and my target is ARM processor. But i
guess it should not matter. Actually i need to know both RAM & ROM
usage.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
