You use output devices or streams, typically console screens, printers and files.
example output of c++ calculator
For basic input and output in C++: #include
Pipe the output to the MORE command.
Whoever said so, they were wrong. For sure "printf" can be used without any problem.
input is the << operator and output is the >> operator
File handling is simply the process of opening, reading, writing and closing files. Files are simply streams for input and output, or the "serialisation" of objects. In other words, reading and writing data to and from disk storage.
Use "typedef" : both in C and C++.
unsigned char [16]

No. In C++ with <iostream>, cin is a prefedined class that represents stdin, so it is an input identifier.
Streams provide a unified, generic, input/output mechanism in C++. They allow a consistent method of inserting or extracting data from any physical storage medium that supports a stream implementation, such as a filestream or a stringstream, without the need to know the details of that medium. All streams operate in exactly the same way. To extract data from an input stream, use the extraction operator (>>). To insert data into a stream, use the insertion operator (<<). Some streams are omni-directional (input-only or output-only), while others are bi-directional (both input and output).
