Pain of codes (from Java to C++)

I never thot that cleaning up the codes is so painful. I'm supposed to repackage a piece of code, making to more presentable. But it brought me pain. I never thought that Java could make harm to C++ coding... I often see code segments like...
  (object) obj = new object(param1,param2,param3);
  (object *) objectArrary =
    new (object *)[someSize];
  if (objectArray == NULL) {
    cout << "ERROR" << endl;
    exit(1);
  }
  :
  :
  :
  delete obj;
  delete [] objectArray;

while the code can be written nicely as...
  object obj (param1,param2,param3);
  (object *) objectArrary[someSize];

I often see variable names like... noOfBindingSites, motifLength.... which I renamed it to num_binding_sites, motif_len... more C++ friendly.

I'm still trying to clear up all this "style of writing C++" to somthing I feel more comforatable... But I'll need to break up a function of 400++ lines into different functions (methods) that are described in a paper by 6 different EM functions. That's the most painful part. Then when I asked why lump all into one? The answer is (justifiable), "because putting into different methods make it *slow*,....", how slow? .... Then I stop asking, I'll do it *MY WAY*.
