Program Plan Intro

Pointer:

Pointer is a special type of variable used to store the address of the memory location, which can be accessed later.

If an asterisk “” operator is present before the variable, then that variable is referred as pointer variable.

It is also called as dereferencing or indirection operator.

Pointer is just a type of variable that stores the addresses of other variables.

Using pointers, it is easy to access the address of a variable; the data stored in that variable can be retrieved.

Syntax of pointer variable declaration:

<variable-type> <variable-name>;

Define the pointers to structures:

Define the pointers to structure is similar to pointer variable declaration.

Example:

//structure declaration

struct student

{

    //variable declaration

    string name;

    //dynamically allocate array

    int score;

    //variable declaration

    int total;

};

Pointer is the definition to the above defined structure that can be given as follows:

//defining the pointer definition

student stu1;

*Java code* Implement a data structure called RunningTotal supporting the following API: a) RunningTotal() - creates an empty running-total data structure b) void add(int value) - adds the given value to the data structure c) void remove() - removes the least-recently added value d) int sum() - returns the sum of values in the data structure e) double average() - returns the average of values in the data structure Here's a Example: RunningTotal rt = new RunningTotal ();rt . add (1); // 1 ( adds 1 )rt . add (2); // 1 2 ( adds 2 )rt . add (3); // 1 2 3 ( adds 3 )rt . sum (); // 1 2 3 ( returns 6 )rt . add (4); // 1 2 3 4 ( adds 4 )rt . remove (); // 2 3 4 ( removes 1 )rt . sum (); // 2 3 4 ( returns 9 )rt . average (); // 2 3 4 ( returns 3.0 )

Would it be possible to use unique, shared or weak pointers in the code?

C++ I need to create a 2D array map that can be displayed in the output like a 2D array visually.
