Fundamentals of Object-Oriented Programming - C++ - Files - CHAR IO RDBUF

The video tutorial covers how to write and read characters to and from a file in C++. It begins with defining a string and writing it to a file using an ofstream object and a for loop. The tutorial then demonstrates reading the file contents using an ifstream object, a while loop, and the get method. Finally, it introduces the Rd. buff function as an efficient alternative for reading file contents.

Explain the two methods mentioned for reading the contents of the file.

What is the role of the Rd. buff function in reading from a file?
