display pointer memory address

First post from a qt newbie.
How can I achieve this in qt4. What header
files would I need to include? If possible a simple code example would be really appreciated.

int variable = 2;
int* pointer = &variable;

cout<<*pointer<<endl; //displays 2
cout<<pointer<<endl; //displays the location of "variable"

Thanks in advance.
Milo

Code:

---

#include <QApplication>
#include <QLabel>
 
int main(int argc, char** argv)
{
  QApplication app(argc,argv);
 
  QLabel label;
 
  int variable = 2;
  int* pointer = &variable;
 
   QString num=QString::number(variable);
   QString p=QString::number(pointer,16);
 
  label.setText("number="+num+"pointer="+p);
  label.show();
 
  return app.exec();
 
}

Mr Death,
Thank you for the fast reply.
Unfortunately the build finishes with the following error.

error: call of overloaded ‘number(int*&, int)’ is ambiguous

Build complains that QString does not seem to have a candidate number() function

This is the same issue that led me to posting. I was unable to find a Qt function to solve the issue and figured I must be missing something simple.

Any ideas ??

I guess its getting confused in the pointer address
try it with double conversion -
QString p=QString::number((double)pointer,16);

Same casting issue it would seem.

Build Error
error: invalid cast from type ‘int*’ to type ‘double’

This should be really straight forward right?

cast it to int:

Code:

---

String p=QString::number((int)pointer,16);

---

this works for me;

i have tested it... it works for int instead of double
QString p=QString::number((int)pointer,16);

edit: i was a lil late in reply... did not saw the above post..:p:D

Thanks a heap for your replies and your solution faldżip of casting to (int).

Still useful after all these years. Thanks.
