C++ Code

Write a program that performs the following:

a) Declare long variables value1 and value2. The variable value1 has been initialized to 200000. Declare the variable longPtr to be a pointer to an object of type long.
b) Assign the address of variable value1 to pointer variable longPtr.
c) Display the value of the object pointed to by longPtr.
d) Assign the value of the object pointed to by longPtr to variable value2.
e) Display the value of value2.
f) Display the address of value1.
g) Display the address stored in longPtr.

#include <iostream>
using namespace std;

int main()
{
  //  (a)
  long value1 = 200000, value2;
  long *longPtr;

  //  (b)
  longPtr = &value1;

  //  (c)
  cout << "Value of object pointed by longPtr: " << *longPtr << endl;

  //  (d)
  value2 = *longPtr;

  //  (e)
  cout << "Value of value2: " << value2 << endl;

  //  (f)
  cout << "Address of value1: " << &value1 << endl;

  //  (g)
  cout << "Address stored in longPtr: " << longPtr << endl;

  return 0;
}

You should write a small C++ program that performs the following tasks: First, your program should read in a set of 5 integers from “standard in” (remember cin). The numbers that you read in will be either zero or positive. If at least one of the five numbers entered is non-zero then your program should calculate the sum of the numbers and report that back to the user using “standard output” (remember cout). Then your program should be ready to...
