pointer
A data type found in computer programming languages such as C++. It is a variable that holds the memory address of another variable.
Dynamic allocation of memory is possible through the use of pointers.
Dynamic allocation of memory is possible through the use of pointers.
Examples using pointers:
int i = 5; // declares an integer with an initial value of 5
int *p = &i; // declares a pointer to an integer and assigns
the address of i to it
cout << i; // outputs the number 5 to the console
cout << &i; // outputs the address of i to the console
cout << p; // same result as above
cout << *p; // outputs the value pointed to by p (5)
*p = 10; // changes the value of i to 10
int *arr = new int n; // creates an array containing
n elements and assigns its address to arr
(dynamic allocation)
delete arr; // deletes the memory space arr points to
(does not delete the pointer itself!)
int i = 5; // declares an integer with an initial value of 5
int *p = &i; // declares a pointer to an integer and assigns
the address of i to it
cout << i; // outputs the number 5 to the console
cout << &i; // outputs the address of i to the console
cout << p; // same result as above
cout << *p; // outputs the value pointed to by p (5)
*p = 10; // changes the value of i to 10
int *arr = new int n; // creates an array containing
n elements and assigns its address to arr
(dynamic allocation)

(does not delete the pointer itself!)

Pointer
A pointer is a data type in many programming languages such as C++, they are basically references to other variables location in memory. Pointers were created to annoy, confuse and make programmers jobs harder.
The pointer points to the pointer that points to the thing that is not a pointer that is pointed to.
