Hello world

1. Create the file pointers.cpp and paste the following code:

#include <iostream>

using namespace std;

int main() {
    int x = 10;
    int* p = &x; // Pointer to x

    cout << "Value of x: " << x << endl; // Output: 10
    cout << "Address of x: " << &x << endl; // Output: Address of x
    cout << "Value at pointer p: " << *p << endl; // Output: 10
    cout << "Address stored in pointer p: " << p << endl; // Output: Address of x

    *p = 20; // Change value at pointer p

    cout << "New value of x: " << x << endl; // Output: 20
    return 0;
}

2. Open a terminal (Ctrl-ñ) and compile the file:

g++ -std=c++20 -o pointers pointers.cpp

This will create the file pointers (the executable!). To run it:

./pointers
