Tell about the freestore (also known as heap). What is put there? How is this done? How does a program access the freestore? What happens to memory that has been allocated but is no longer needed?

What will be an ideal response?

The freestore is a special area of memory that is reserved for dynamically allocated
variables. Any use of the operator new to allocate space will allocate from the
freestore. The run-time support package for C++ includes a freestore manager.
Operator new causes the freestore manager to allocate memory and return a pointer
to the newly allocated memory. The program that has allocated freestore memory
should return no longer needed memory to the freestore manager by use of the delete
operator on a pointer to the memory.
