Chapter 12, Problem 15SA

Explanation of Solution

The problem with the program has been explained in the in-lined comments:

#include <iostream> 

using namespace std; 

int main()  

{  

    //pointer variables declared and memory allocated

    double *firstPtr = new double; //Line 1

    double *nextPtr = new double; //Line 2

    //value assigned to pointer variable

    *firstPtr = 62; //Line 3

    //nextPtr is assigned the pointer firstPtr

    //so nextPtr points to a memory location

    //having a stored value of 62

    nextPtr = firstPtr; //Line 4

    //memory pointed to by both the pointers are

    //deallocated

    delete firstPtr; //Line 5

    delete nextPtr; //Line 6

    //fresh memory i...
