C++ Modify Pointers

Modify the Pointer Value

You can also change the pointer's value. But note that this will also change the value of the original variable:

Example

string food = "Pizza";
string* ptr = &food;
// Output the value of food (Pizza) cout << food << "\n"; // Output the memory address of food (0x6dfed4) cout << &food << "\n"; // Access the memory address of food and output its value (Pizza) cout << *ptr << "\n"; // Change the value of the pointer *ptr = "Hamburger"; // Output the new value of the pointer (Hamburger) cout << *ptr << "\n"; // Output the new value of the food variable (Hamburger) cout << food << "\n";
