Short Answer

Expert verified

Answer: Yes, the specified file will be erased if it already exists when calling an ofstream object's open member function in C++.

Step by step solution

Understanding ofstream objects

ofstream objects are output stream objects used to manage (open, write, and close) files, mainly for writing values and texts into files.

Investigating the open member function behavior

When calling the open member function on an ofstream object, the default behavior is to discard the file's previous content and start writing from the beginning. In other words, if the file already exists, it will be erased (truncated), and writing will begin at the beginning of the file.

Evaluating the statement

Based on the behavior of the open member function of ofstream objects, the statement is true. When you call an ofstream object's open member function, the specified file will be erased if it already exists.
