Pointer: Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “” operator is present before the variable then that variable is referred as pointer variable.

Chapter 9, Problem 60RQE

Program Plan Intro

Pointer:

Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “” operator is present before the variable then that variable is referred as pointer variable.

Consider the following statement:

//definition of pointer variable

int ptrvar;

Here the variable “ptrvar” is defined to a pointer variable of integer data type. So, it can store the address of an integer variable.

Returning a pointer from the function:

Pointers can be returned from the function only if the reference pointer variable that points exists in the function.

Circumstance for successful return of a pointer:

The circumstances for returning pointer successful are listed below:

When a pointer is passed as an argument in a function that is called.

When a pointer variable is defined locally within the function there may be possibility for the contents of the variables being destructed after execution of the function. This can cause unexpected results.

When pointer gets chunk of memory allocated dynamically.

When a variable is allocated dynamically, the contents will be available until the compiler executes the “delete” operation.
