How to convert assembly to executable in c programming..

And also tell me how to view the c program opcode............

Read the assembly and rewrite it in c maybe?

Start here.

http://www.catb.org/~esr/faqs/smart-questions.html

gcc -c file.s
You should get file.o and link it with all other .o files you need to make executable. Or, if that's the only file:
gcc -o executable_name file.s

C doesn't matter at this stage.

gcc -S program.c
It converts your C program to assembly code.

You can also assemble your code with the GNU as assembler, and link it with ld:

Assemble:
as -o program.o program.s

Assemble with debugging info (for gdb):
as -gstabs -o program.o program.s

Link static executable:
ld -o program program.o

Run:
./program

i agree with mara.

symantically 3gl's (c, c++, java...) are compiled down into machine code (hex).

assembly interprets opcodes into machine code.

so based on how efficient the compiler is, it should be similar to the machine code created by the assembler. (i.e.- a binary executable is a binary executable regardless of being sourced by c, c++, python...)

that is why you can view the machine code and it's generated opcodes while stepping through an instruction using dbx or gdb.

however, the machine code and respective assembly will be different according to which processor is used (primerilly moto 68k or intel x86)

comments?

Just one thing to add, Java and Python scripting language are not exactly compiled. That is until the parser receives the Python script or the JRE receives the byte code. Java is semi compiled and optimized for the Java interpreter, it is binary, but not the executable kind for your architecture. These wrappers (JRE and Python) compile and execute just-in-time. Assembler, C and C++ can be compiled into true executable binaries.

Also, hex is just a way of READing or interpreting the bits, it is still binary. Just thought I would mention, what I think you probably already know (just in case).

Anyhow, you could also use a ASM wrapper in your C/C++ IDE. I would do these when writting 68K ASM for palm pilots in codewarrior. It was a more elegant solution than having both the ASM and C code separate.

On as regrds convert know good tool.

Why are you think that i spammer? I helped peoples,for convert my friends lately tolded me about utility- <...snip>

^remind me again how outlook express email backups have to do with converting assembly language opcodes into machine language binary.

whatever your talking about has nothing to do with this thread -- reported as spam.

There are two connections between C and assembler:
1.) use C code with embedded assembler source (consult your C compiler docs for details)
2.) write an assembler in C, and run it against your assembler source code.
