decompiling back to C++?

uncompiler is not a easy thing...
it needs more other experienced KB.
and more symbols and debug info ar lost during compiler,
so uncompiler endeaver recover these thing.
such as..
source code:
void SwapTwoNumber(int* a,in* b)
{.................
}

via uncompiler may be in these form:
sub_0121(DWORD* a1,DWORD* a2)
{......
}

yep,SwapTwoNumber is info, u maybe will soon master some funcs by name,,
So uncompiler will try to recover these name,this can be attained by AI.
the above is one easy instance...
Had time,we can dicuss these techz in detail..
