Question

Write a C++ program to do the following:

1. Declare and assign values to int variables x, y
2. Declare an int variable z; and store the sum of x and y in it
3. Declare a pointer called pz and point it in the heap direction (using new)
4. Store the z value in the heap location using the pz pointer
5. Print the content of the pz pointer
6. Print the pointer (the address)

Answer 1

#include <iostream>

using namespace std;

int main() {
    // Declare and assign values to int variables x, y
    int x = 5, y = 7;
    // Declare an int variable z; and store the sum of x and y in it
    int z = x + y;
    // Declare a pointer called pz and point it in the heap direction (using new)
    int *pz = new int;
    // Store the z value in the heap location using the pz pointer
    *pz = z;
    // Print the content of the pz pointer
    cout << *pz << endl;
    // Print the pointer (the address)
    cout << pz << endl;
    return 0;
}
