hmmm, i'm not aware of any out there, if there is it could be dangerous...or if there is it's not very accurate, cause there are so many compilers out there and they all compile to assembly code, differently, that's why some c++ compilers produce faster executables than others while some produce safer code that others...in other words, no i don't think there is, but there are some out there that will decompile to assembly code...so if i were u i'd brush up on complex assembly language routines, cause that's all u'll get...sorry

There is no such an application. C++ compiler generates machine code. You can use disassembler to see machine instructions from EXE

Actually, I have heard of dissasemblers that produce high-level language output, like C or C++ output.  I have never used one though and I can't give you any product names.  However, their ouput is likely to be very poor.  Unless debug symbols are included in the program, it will not be able to provide the original names for variables, procedures, or constants.  It will instead number these things like VAR0001  VAR0002 etc.  Not very friendly.  However is still legitimate high-level language output and is probably easier to manipulate and recompile than assembly.

galkin happens to be incorrect this time.  I have seen a "decompiler" that produces Pascal code.  Now, as nietod mentioned, the relation of the output to the original source will be conicidental at best.  However, if the original program was in fact compiled with the language in question and WITHOUT ANY OPTIMIZATION, the result can be semi-readable.

Yes, I've been told by one of by friends that there is a decompiler, but it is for DELPHI, curentally speaking I am downloading it right now.
