Pointer: Pointer, the name itself references the purpose of the pointer. Pointers point to a location in memory. Pointer is a special type of variable 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, we can access the address of a variable; the data stored in that variable can be retrieved. Syntax of pointer variable declaration: <variable-type> <variable-name>; Adding a value to a pointer variable: When a pointer variable is added it is similar to adding number of time the size of the pointer variable that is stored. Example: //declaring a pointer variable int a; //incrementing the pointer value by 1 a++; In the above snippet the pointer variable is incremented by “1” means, the size of the pointer variable is being increased in terms of their size. 1 2 = 2 Therefore, additional 2 bytes will be added to the pointer variable “a” after incrementing it by “1”.

Program Plan Intro

Pointer:

Pointer, the name itself references the purpose of the pointer. Pointers point to a location in memory.

Pointer is a special type of variable 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, we can access the address of a variable; the data stored in that variable can be retrieved.

Syntax of pointer variable declaration:

<variable-type> <variable-name>;

Adding a value to a pointer variable:

When a pointer variable is added it is similar to adding number of time the size of the pointer variable that is stored.

Example:

//declaring a pointer variable

int a;

//incrementing the pointer value by 1

a++;

In the above snippet the pointer variable is incremented by “1” means, the size of the pointer variable is being increased in terms of their size.

1 2 = 2

Therefore, additional 2 bytes will be added to the pointer variable “a” after incrementing it by “1”.

Using C++ Programming language: Given the following definitions: int num1=1, num2=2; int *ptr1=NULL, *ptr2=NULL; Write the following statements: Assign ptr1 to the address of num1. Assign ptr2 to the address of num2. Using pointer notation, write a statement that compares the values that the pointers "point" to to see which is larger. (There is more than one way to do this. You choose.)

Using C++ programming language: Assume intptr is a pointer to an int. Write a statement that will dynamically allocate an array of 100 integers and store its address in intptr. Also, write a statement that will free the memory allocated in the statement you just wrote.
