Define Cin and Cout in C++?

Cin and cout are two important functions in C++ that you should know about. Cin and cout are functions that allow you to read and write data to a stream. The basic syntax of cin and cout is as follows:

• cin(stream) - Read data from the stream.
• cin(stream, value) - Read data from the stream and assign a value to the variable.
• cout(stream) - Write data to the stream.
• cout(stream, value) - Write data to the stream and assign a value to the variable.

The first function cin takes a stream as an argument and reads data from the stream. The second function cout takes a stream as an argument and writes data to the stream. You can use cin and cout to read and write data from a file, a database, or any other source of data
