Cite your reference.

ANSWERS:As i research in the internet there are too many assembler use like,Nasm,Goasm,Tasm,Gsm,Masm and Fasm...But the best assembler that i found out seems to be a good assembler is the FASM .Why? because Fasm(flat assembler)is a free and open source intel-style assembler supporting in the IA-32 and x86-64 architecture. Fasm known for its fast speed, size optimization, OS portability, and macro capabilities.it contains also binding to the windows GUI and open GL.

The output of fasm can directly through any of this following, flat "raw" binary,objects: ELF or COFF, executable in either MZ,ELF or PE format.
