What does de-referenced mean?

What does de-referenced mean?

Code:

	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:

Code:

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;

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