[comp.lang.c++] Efficiency Questions about C++

konopka@cbnewsk.att.com (raymond.konopka..jr) (08/29/90)

I have been conducting some research into the possible move from
C to C++.  The main questions which I still have not received 
answers for pertain to the area of efficiency.  Below is a list
of questions that I need answered:

1. How does the execution time of a C++ program compare to a 
   C program accomplishing the same task?

2. Is C++ fast enough for use in real-time programs (or is there
   too much overhead)?

3. I have heard that C++ is really a preprocessor which converts
   C++ code into the standard C language code.  Is this true and
   if so how does it work?

4. Are there any addition memory requirements (or overhead) which
   don't exist in standard C?

I would appreciate any information regarding any of these questions.
Feel free to e-mail the responses to me if you don't think they 
should be posted.

Thanks,
