📌 Why Learn cin?
The cin object (pronounced "see-in") is essential for accepting user input in C++ and is the counterpart to cout. cin is an object of istream class that is used to accept input from the standard input stream (stdin), which is by default associated with the keyboard . Understanding cin is fundamental for creating interactive programs that respond to user actions.
💡 What is cin Statement?
cin is a predefined variable that reads data from the keyboard with the extraction operator . It's part of C++'s iostream library and works together with the (extraction operator) to capture user input and store it in variables. The extraction operator is used along with cin to extract data and insert it into variables.

🔗 How cin and cout Work Together:
cout is pronounced "see-out" and is used for output using the insertion operator , while cin is pronounced "see-in" and is used for input using the extraction operator . Both are part of the iostream library and work together to create interactive programs.
