Is there any software or method which can convert Assembly Language to C Programming Language???

 

This is like recreating the egg from the omelette - it's not possible, the information no longer exists.

Of cause there is. It's called a decompiler and it probably came with your compiler and assembler.

Interesting suggestion, perhaps you could give an example? - I've never seen any such thing in all the compilers I've used over the years.

That would make for a hacker's wonderland wouldn't it?

 

Decompilers exist for many different architectures and languages. However, the output is likely to be worse code than the input. You'd learn more just doing the conversion the old-fashioned way: reading the asm and writing the corresponding C yourself.

Among other things, symbol names and some other information is lost. The output will be very literal and probably not particularly easy to read.

Again, the tools are not perfect and it's usually easier just to learn to read the assembly.

It's not IN a compiler. It's a separate program that you feed the asm to and you get out a very confusing compiler version. The output generally does not use headers and includes so you get out ALL the code needed to assemble the asm.

It's most confusing and like Torben said it would be much easier to learn ASM.

I've read many 'asm to C' attempts to decompile in a sensible symbolism, all of them are at best half-assed. They usually use simple proper noun replacement to try
to help native understanding of the converted code, and it's always bad.

Bob is my uncle, my uncle is 3.1415926 positive times in relation to itself and his father is 3 less than his mother is 1 more than her daughters last mood change.

If you just want to use the ASM code in a C environment use an inline ASM argument, most C copilers support this if the ASM memory/code structure is known.

Thats tough to do. There are so many assembly combinations out there for a set of C instructions, that it makes this very difficult. If you want it done right, you're best off doing it yourself.

I never suggested it was internal to the compiler, just included (or rather not) in the compiler package.

I'll ask again - can you give an example of any such compiler package?.

Just Google it. There are loads of them.

Really all program languages are built from machine code which directly correlates to the assembly language mnemonics. You would have to reverse engineer it yourself. I suggest getting "WinDbg.exe".

here's a one link: http://bytes.com/forum/thread657053.html

 

Salgat is right. There is not a 1:1 mapping between source code and the asm generated from it. Things get even worse if the code is optimized.

Olly Debug is pretty good

 

That's just lazy. Earlier you stated that:

I'm with Nigel. While decompilers exist and while there are examples of compiler/decompiler packages, they are not the norm and the statement that "it probably came with your compiler and assembler" is not true.

Unless of course you feel like providing some links to back up your statement. It's not our job to defend your position. If you can't be bothered to, why should anyone else?
