Pointer?
A pointer references a location in the memory. In simple words it keeps the address of the memory where actual data is stored. Obtaining the content of the pointer is called deferencing the pointer.
Pointers to data significantly improve performance for repetitive operations such as traversing strings, lookup
tables, control tables and tree structures. In particular, it is often much cheaper in time and space to copy and dereference pointers than it is to copy and access the data to which the pointers point. you can learn more about pointers here.
