Why do several function in iostream and fstream have identical names?
The iostream and fstream classes are part of the same inheritance tree in C++, so they share common functionality. This means that both classes have functions with identical names to provide consistent behavior for input/output operations. The functions in iostream are generally for text-based input/output, while those in fstream are specifically for file-based operations.

It's a bit difficult to show a class hierarchy using unformatted text alone, so I'll use the scope resolution operator to show the relationships instead.
