It's not as bad as it seems.
You might be thinking a lot of "translation" is needed. It's really not that bad.
...that wont have to be translated into new code to get them to work?
1- Add: using namespace std;
2- Drop the dot-h from the standard header files
3- Add 'c' to the old c-header names: <time.h> becomes <ctime>.
You can find a list of all the standard headers (and their functions) at Dinkumware.com. Note - you have to click-thru the sales pitch to get the free reference at Dinkumware.
That should do it!
