Is the HEAP a term for ram, processor memory or BOTH? And how many unions can I allocate for at once? : <p>I was hoping someone had some schooling they could lay down about the whole HEAP and stack ordeal. I am trying to make a program that would attempt to create about 20,000 instances of just one union and if so some day I may want to implement a much larger program. Other than my current project consisting of a maximum of just 20,000 unions stored where ever c++ will allocate them do you think I could up the anti into the millions while retaining a reasonable return speed on function calls, approximately 1,360,000 or so? And how do you think it will handle 20,000?</p>
