Assembly to c++ converter
Hi i need a assembly to c++ converter, but i only found a c++ to assembly converter. Can anyone reverse this c++ to assembly script so it will be c++ output here is the script
#define N10
main()
{
int i;
int array[N]={2.4,7,8,14,5,13 ,23};
int accumulate =0;
for(i=N-1;i>=0;i--
{
accumulate += array[i];
}
cout<<"the result is"<<accumulate<<endl;
}
really need your help.

AFAIK an assembly to c++ converter does not exist. There is a lot lost in translation when compiling.
Any c++ compiler can give you assembly code though (or at least the ones I've used). I generated some assembly for your code, I just removed the line with 'cout', because it means including iostream and the listing would become _a lot_ bigger.

I am not sure what you can do with this though.. The only reason I see for looking at assembly code is to learn about assembly and compiling or about how your compiler optimizes things.. Anyway, good luck

Hi, I need a C++ to assembly converter. You seem to have one. Please can you send it to me or give a link from where I can download?
Thanks in advance

Well I guess every compiler is a C++ to assembly converter.. In visual studio 2005 there is an option under configuration properties|C/C++|output files. For gcc and bcc32 you can specify the -S option on the command line to make the compiler output assembly.

Thanks a lot. I did not know about that feature.
Now the problem is that I want an assembly code generated for micro-controller 80C51 and PIC16F84
Do you know if there is any compiler that helps convert into chip specific assembly code? Can it be done with visual C++ 2008 express edition?
Thanks again.

I guess you need a specific compiler to compile to those micro-controller. I doubt visual studio express can do that. But I am really not into embedded stuff so I might very well be wrong.
