Do you mean assembly as in bioinformatics?

There you would be using something like Velvet.

If you mean where do I find an assembler:

/usr/bin/as on a CentOS system.

Thanks sir

but which tools i have to use to doing program?

The tools you need are;

1. A brain

2. A computer

3. An editor

4. An assembler (the Assembly compiler)

5. A linker

:-)

@Fernando : you forgot an input device to the computer (e.g. a keyboard). :-)

thanks lambert

but i want to run program in which tools ? like c program compile and run in TC.

You can try with FASM and NASM...

VisualStudio C++ would not even allow inline assembly language anymore. Switch to the compiler intrinsics. I did MASM for about 20 years, than inline assembly in C++, but it is all unnecessary for all computational stuff. VC++ has hundreds of intrinsics.

I am not sure if Intel C++ allows inline assembly
