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.

What method is used to determine the size of a string in the context of writing to a file?

• string.length()

• string.size()

• string.capacity()

• string.max_size()

Which method is used to write each character of a string to a file?

• write file dot append

• write file dot insert

• write file dot add

• write file dot put

What is the purpose of the read file dot get method?

• To close the file

• To delete data from a file

• To write data to a file

• To read each character from a file

Which function is a member of the iOS class used for reading file contents?

• Rd. write

• Rd. read

• Rd. get

• Rd. buff

What is the advantage of using the Rd. buff function?

• It reads data more efficiently

• It compresses the file

• It encrypts the file

• It writes data faster
