decompiling back to C++?

with me.
it's possible.
but convert this what for?
without understand of algorithm, a program like a death body.

i don't know any program to do that but anyone can convert it manually.

each c++ compiler has a own way to generate code from c++ to c and then from c to asm.

so if you want to convert code from program to c++ you must:
+ convert machine code to asm - ida pro can handle almost
+ convert this asm to c - the hardest step @@!!!@@
+ depend on what compiler that generated this code, convert this c code to c++ code - the easiest step.


hope this can help you.
