Hi guys, currently doing some homework to improve my skills. Not sure is it the place to post this question here, so I apologize first if I posted in the wrong section. This file is having vulnerability to let me exploit, so I guess to ask in this Security Discussion.

I tried to run a file by using gdb, but I encountered 2 errors as shown in the picture below.

#0 0x08059081
#1 0x080493c6

May I know what is #0 and #1? I would like to know what is this "0x08059081" is called. The name, address or reference something like that? And how can I know its value? Is there some way to determine its value or name etc?
