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;
