A way to print with memory address in gdb

Is there a way to include the memory address whenever printing something in gdb. For example:

>>> p __libc_argc
$4 = 1

Instead, I'd like to have:

>>> p __libc_argc
$4 = 0x7fffffffec63  1

To print the memory address of a variable just add & before its name. If you often want to print both the variable address and its value it might be worth creating a command for that. For instance, add the code below to your .gdbinit file

define pwa
  print &$arg0
  print $arg0
end

With this, you will have a pwa command (short for "print with address") that you can use instead of the standard print command whenever you want both the address and the value to be printed.
