Pointer stores the location in memory of the data it points to. "Referencing" the data with the * operator lets you get the info it points to. To store the data, you "dereference" it with the & operator. At least I think thats the terminology.

A pointer usually stores the address of another variable.

Jackson Oā€™Donnell Dereferencing not referencing a pointer is getting its value ;) int x = 5; int* p = &x; //& before variable gets its address std::cout << *p; // dereferencing - cout shows "5"
