Dennis and Brian, thanks a lot. I wonder if you can tell me where I can get more information on interpreting these output.

() > Cannot access memory at address 0x69616c70 I wonder why we don't interpret 0x2073746e instead of 0x69616c70 (which is the memory address) as a string of chars. We know 0x69616c70 is the address but what is 0x2073746e ? Sorry for prolonging this subject too much. If you can tell me some source to read about for details it will be very appreciated. Tnanks a lot in advance.
