The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

objdump

Asked by codenamecharlie in Linux

Tags: objdump, exec_p

On Redhat, I tried this simple program:

int main(){return 0;}

I used gcc to compile it into a.out, then ran this command:

$ objdump -x a.out

The beginning several lines look like this:

a.out:     file format elf32-i386
a.out
architecture: i386, flags 0x00000112:
EXEC_P, HAS_SYMS, D_PAGED
start address 0x080482f0

I found this in the symbol table:
080482f0 g       .text  00000000              _start

so the start address 0x080482f0 points to the routine _start.
My question is just: why start address is always 0x080482f0
for all program I tried? Why this value, why not any other value?
I know this address is virtual memory address.

Thanks,
