what is the importance and usage of assembly code nowadays?

Answer 1

Assembly still has a variety of uses. It is often used in AAA games, Flight Control software, embedded hardware (as Bernd pointed out) and various other things. Although c/c++ compilers are excellent at optimisation and are getting better everyday there are still instances where manual assembly outperforms.

Answer 2

Yes we can program directly in Assembly.
See here for a short introduction to x86 Assembly:
http://www.cs.virginia.edu/~evans/cs216/guides/x86.html

There is also x64 Assembly:

Answer 3

Yes. It can be used to reverse engineering a program. But you will not see the actual code used to create the original program. If you search youtube there are several videos which demonstrate this using custom programs for you to practise on. It is not really the primary function of assembly though. It has many constructive uses

Answer 4

Just a side note: Writing a full GUI application purely in Assembly is not really a great use of ones time.

You are much better off using c/c++ to do so. then if you discover bottlenecks are present that cannot be optimised out using c/c++ then use assembly.

Answer 5

Just a side:

(the MASM that can be installed without installation of Visual)
(What I mean is Officical MASM must install Visual which is not free)

Answer 6

you can still program little microcontrollers, e.g. used in washing machines or to control electronic stuff. look for atmel Studio and Start with atmega16 tutorials. unfortunaltely u will need Windows for using atmel Studio IDE since the company has sold its soul to Microsoft

Answer 7

nice bernd i will look for it, I was searching for assembly and discovered that when Intel amd or any other manufacturer add new features to the processors sometimes the only way to access this features is with assembly scripts

Answer 8

im interresed in the begin of programation, sorry for any english mistake im brazilian and my english isnt so good at now

Answer 9

thanks jay i iwll study in this sites

Answer 10

understand, i think the assembly can be used in cracker programms because once you run a code is difficult to do a reengeenering
