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.
What else can I help you with?
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.
What does the file pointer return?
The file pointer, often used in programming to manage file input and output, returns the current position within a file. It indicates where the next read or write operation will occur. Depending on the context, it can also provide information about the file's end, allowing for efficient data processing and manipulation. Functions or methods associated with file pointers can typically move or adjust this position as needed.
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()
Which function is used to determine the position of the put pointer in the file?
pos_type tellp();
What function will read a specified number of elements from a file?
The function fread() in C can be used to read a specified number of elements from a file. It takes as arguments the pointer to the buffer, size of each element, number of elements to read, and the file pointer.
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 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.

If you delete something from your computer such as music and movies does it free up the space on your hard drive completely or does some of it remain?
Answer:When you delete something such as music, video, or documents, a pointer (a small piece of code) for the file itself is what gets sent to the trash. This pointer, along with other pointer for every folder and file on the hard drive, is saved in a section near the beginning of the hard drive and is used by the operating system to create a directory. When you clear out the trash, the OS realizes that the pointer is gone, and then marks the section the file is at as writable. So basically the file never really gets sent to the trash, but gets written over.
What is an NB file?
This is a file used for mathematical computation. It may store text/documents, audio, images, and functions.
