    Question What does de-referenced mean?

    What does de-referenced mean?

  2. #2
    	int num = 100;
    	int* ptr = #
    	cout << *ptr << endl;
    Derefencing the pointer (ptr) gives access to the value of the variable that the pointer is pointing at. If the line was:

    cout << ptr << endl;
    then I would just be printing the value of the pointer, ie an address.

    Dereferenced means "give the contents of the address pointed to". So if
    int *p = &i;

    cout<< p <<"\n"; // Prints the address of i
    cout<< *p <<"\n"; // Prints the value of i

    My best code is written with the delete key.
