    Solution

    The #include directive in C and C++ is used to include the Standard Input Output library header file in a program. This header file contains the declarations of functions for performing input and output operations, such as printf for output and scanf for input. By including , a program gains access to these standard I/O functions, allowing it to interact with the user through the console or terminal.
