Pointer Address in C++

A simple program that I wrote a long time ago in C++ that shows how to use pointers to know the memory address of the variable. The code is very short and easy to understand.

Program Listing

#include <iostream>

using namespace std;

main() {

    int value = 10;

    int *ptrvalue;

    ptrvalue = &value;

    cout << "The original value is " << value;

    cout << "\n\n";

    *ptrvalue = 20;

    cout << "The new value is " << value;

    cout << "\n\n";

    system("PAUSE");

}
