How to view C object code using objdump?
In computing and programming, most higher level programming (C/C++) are converted/interpreted into a lower-level language through a compiler. Generally the output from the compiler is object or assembly code which are pretty low-level languages.Using objdump, we will be able to view the object code from a compiled C program.
How to use objdump to disassemble ARM code?
If you want to do disassemble of ARM code, you’d better have an ARM tool chain, this is what I got: After you have this, you can use arm-elf-objdump instead of objdump. The command I used is If you look the manpage, you will find “-b” is followed by the file type.

How to view an elf file in objdump?
Objdump is a program that displays information about inputted object files. The object file that is created when code is compiled is an ELF (Executable and Linkable Format) or as we will see it, “a.out”. We can take this object file and use Objdump to view the programs object code I will be compiling my C code in gcc.
