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.

Analyze the following code.
``` // Program 1: public class Test { public static void main(String[] args) { Object a1 = new A(); Object a2 = new A(); System.out.println(a1.equals(a2)); } } class A { int x; public boolean equals(Object a) { return this.x == ((A)a).x; } } // Program 2: public class Test { public static void main(String[] args) { Object a1 = new A(); Object a2 = new A(); System.out.println(a1.equals(a2)); } } class A { int x; public boolean equals(A a) { return this.x == a.x; } }``` a. Program 1 displays true and Program 2 displays true b. Program 1 displays false and Program 2 displays true c. Program 1 displays true and Program 2 displays false d. Program 1 displays false and Program 2 displays false
