hey all...

i'm having issues with a data structures assignment and could use some help if anyone has some insight. the short version is that i need to dynamically allocate space for a stack based on user input at run time, but i'm unable to use new/malloc or any other operator for space in the heap...apparently we're supposed to use only the stack. i've been researching for a while, and the best i can come up with are vectors. does anyone know if they use heap memory, or have any other ideas? any help would be greatly appreciated.

thanks,
brian
