Functions_used_for_manipulation_of_file_pointers_are_as_follows:">Functions used for manipulation of file pointers are as follows:
seekg():_Moves_get_pointer_(input)_to_a_specified_location.">seekg():Moves get pointer (input) to a specified location.
seekp():_Moves_put_pointer_(output)_to_a_specified_location.">seekp():Moves put pointer (output) to a specified location.
tellg():_Gives_the_current_position_of_the_get_pointer.">tellg():Gives the current position of the get pointer.
tellp():_Gives_the_current_position_of_the_put_pointer.">tellp():Gives the current position of the put pointer.
The seekg & tellg functions are associated with get pointer and seekp & tellp functions are associated with put pointer.

Which function is used to determine the position of the put pointer in the file?
pos_type tellp();
Which function is used to move file pointer from any position in file in c language?
FILE-level: ftell/fseek, fgetpos/fsetpos handle-level: lseek
What are the application of this pointer can you use this pointer in friend function justify?
The this pointer can only be used within nonstatic member functions. Friend functions are not members so they have no access to a this pointer. However, you can pass a specific instance of a class to a function via a class reference argument. To understand how friendship works, first understand that a nonstatic member function has the following properties: 1. It has private access to the class. 2. It is scoped to the class. 3. It must be invoked upon an object of the class (has a this pointer). Static member functions have the first two properties while friend functions only have the first property.
Library functions in C programming?
They are very important. The most commonly used functions are the string and file handling ones.
How does virtual function support run time polymorphism?
Virtual functions are used to suport runtime polymorphism.In C++,if we have inheritance and we have overridden functions in the inherited classes,we can declare a base class pointer and make it to point to the objects of derived classes.When we give a keyword virtual to the base class functions,the compiler will no do static binding,so during runtime ,the base class pointer can be used to call the functions of the derived classes.Thus virtual functions support dynamic polymorphism.
Which function is used to determine the position of the put pointer in a file in c plus plus?
The function ftell returns the position of the file pointer for a file.
Which function is used to determine the position of the put pointer into the file?
tellp()

What is header file in computer programming?
A header file is used in some languages to declare functions that will be used but are not yet defined in the current source code. This is primarily used by C and C++, and usually for library functions and user-defined functions that are stored in separate files and folders than the main source code file.

What is an NB file?
This is a file used for mathematical computation. It may store text/documents, audio, images, and functions.
Which header files contain declaration for the files input and output functions and the macros defined and that are used with file input and output functions?
stdio.h
What is a TCP IP protocol that is used for file manipulation?
As per the MCSE guide to Windows XP Professional second edition pg. 317 the answer is FTP.
What is the technique used for adding and subtracting values from the pointers address in order to access other memory locations called?
WikiAnswers does not provide information about illegal acts, such as cracking other computers through pointer manipulation.
