By default, all the files in C++ are opened in which mode ?
The correct answer is B) Text
In C++, when you open a file without specifying a file mode, it is opened in the "Text" mode by default. The "Text" mode is also known as the "Textual" mode. In this mode, the file is treated as a stream of human-readable characters. It is the most common mode used for reading and writing text files in C++.
