Cout

Cout is a standard output stream object in C++ used for printing data to the console, typically the terminal or command-line interface. It is part of the iostream library and is commonly used with the insertion operator (<<) to display variables, strings, and other data types. This tool is fundamental for debugging, user interaction, and logging in C++ applications.

Also known as: std::cout, cout, standard output, console output, C++ output stream

Why learn Cout?

Developers should learn Cout when working with C++ to output information for debugging purposes, such as checking variable values or program flow, or for creating command-line interfaces that provide feedback to users. It is essential for basic console applications, educational programming, and any scenario where real-time text output is needed during development or execution.
