    <p>I wrote a small program to add to integers and on using "readelf -a executable_name" it showed the entry point address in elf header as :</p> <pre><code>Entry point address: 0x8048330 </code></pre> <p>How my executable knows this address beforehand even before loader loads it in memory ? elf_format.pdf says this member gives the virtual address to which the system first transfers control, thus starting the process. Can anyone please explain what is the meaning of this statement and what is the meaning of virtual address here ? </p> <p>Also let me know, from where the executable file gets the value of 0x8048330 as entry point address. just for cross check i compiled another program and for that also, the entry point address remains the same value 0x8048330 (offset of .text section being 0x330 in both the cases).</p>

    1. COLook up Wikipedia for virtual address or virtual address translation or virtual memory, etc, if you're interested. Unless you are making your own OS with any of those, for your purposes it's not needed to know what they are, just drop the word virtual. There are also tools, which should be able to tell you a lot about executables. Try objdump.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
