I have trouble with operations related to input and output operations. How can I use the incorporation of the input and output operations in the context of C++ programming? 

Answered by Chloe Burgess

The #include iostream.h is a command in a C++ program. It signifies the incorporation of input/output operations. Therefore, this command allows C++ to grant access to fundamental input and output functions, such as cin and cout. It allows also interaction with the console. However, one fact you should remember is that in modern C++ programming language, the standard way to include a library is used without the .h extension.

 This library usually provides functionalities for input from the user through the keyboard in the form of cin and output to the console in the form of cout. It also simplifies the process of input-output process, making it easier to provide and display information. When the user receives input he creates interactive console programs. Therefore, in conclusion, the use of isotram include is very much beneficial in input-output management, however, the “.h” extension is not vague and replaced by an updated form in the field of C++ programming language.
