Choose the correct option. ios::in and ios::out are input and output file opening mode respectively. Options true false can't say

Understanding File Opening Modes in C++

1. Break Down the Problem

   We need to determine whether the statement about ios::in and ios::out is correct regarding their roles as file opening modes.

2. Relevant Concepts

   • In C++, the fstream library provides file handling functionalities.
   • The ios class in this library offers several file open modes, including ios::in for input operations and ios::out for output operations.

3. Analysis and Detail

   • ios::in allows reading from files, meaning it opens a file for input operations.
   • ios::out allows writing to files, meaning it opens a file for output operations.
   • Therefore, both ios::in and ios::out are indeed the correct modes for input and output respectively.

4. Verify and Summarize

   The definitions of ios::in and ios::out are consistent with file handling operations in C++. Hence, the statement is verified to be true.

Final Answer

true
