Explore the read( ) and write( ) functions for reading and writing binary files in C++ within this lecture.

Explore the read() function for C++ binary file handling, showing how it reads one record at a time using a final object and a size argument.

Learn how the write function appends a record to a binary file by passing the object's address and size, using reinterpret_cast to char*, and comparing with read.

Learn how file pointers point to specific positions in a file, like start, middle, or end, and how get pointers read while put pointers write in text and binary files.

Learn how seekg repositions the get pointer for file reading, using two-argument and one-argument forms, with positions from beginning, current, or end; call it on an input stream like ifstream.

Use tellg() to find the current get pointer position while reading a file, returning the byte offset from the file start. Assign the value to an integer.

Discover how seekp positions the put pointer for writing in a file, using beginning, current, or end offsets to place data at bytes like 0, 10, or 100.

Learn how to use the tellp function to determine the put pointer position in bytes during C++ file writing, guiding write operations from the beginning in a console project.

Move file pointers to different positions within a text file to read and replace characters using file pointer functions. Close the file after performing the operations.

Demonstrates writing a class object to a binary file with a write function and reading it back using read, then printing the retrieved data.

extend example seven by writing multiple stone records to a binary file using write and reading multiple stone records with read in loops, then close the file.

explores writing multiple student records to a binary file and reading them back, using a do/while and a while loop to append and print records from the file.

Learn how to implement object oriented programming in C++ file handling by refactoring main into functions, adding a class with disk in and disk out operations, and counting records.

Open example 8 and modify it to meet requirements. Save the file as ex 10 and write records to it based on user choice, then read records from the file.
