I found my C++ Pointers and Dynamic Memoery Management Book!  It was in my 6
year daughter's book trunk (no accounting for good taste :-). For some reason
she thought I gave it to her, so now I have a beutifully decorated Table of
Contents with "Haley Boock" and a heart at top in marker!

In C++ you must cast the allocation.

------  Code snip START ------
 int iCnt;
 STUFF *stuffit;
 stuffit =(STUFF *) malloc(sizeof(STUFF));  // This is the traditional C method
// stuff = new STUFF;  // here is C++'s answer to malloc

// Add Stuff
for(iCnt=0; iCnt<10, iCnt++)  {
	// in C++ there is no high level way of remallocing like with new
 	stuffit = (STUFF *) realloc(stuffit, (sizeof(STUFF) * (iCnt+1)) );
            // add stuff here.
 }
------  Code snip END ------

Thanks for all the help!
