Which statement about the cout command is correct?

The statement that cout is used to output text to the console is accurate. In C++, cout is an object of the ostream class that facilitates displaying output. When you use cout followed by the insertion operator (<<), you can send various types of data, including strings, numbers, and more, to the standard output stream, which is typically the console. This is a fundamental aspect of C++ programming, as it allows interaction with the user by providing a way to display information clearly and effectively.

In contrast to this correct statement, other options do not align with the functionalities of cout. For example, cout is specifically designed for output purposes rather than input; hence, it is not used for reading user input, which would typically involve cin. Additionally, cout is fully capable of handling string data types, so suggesting that it cannot handle them is inaccurate. Furthermore, while cout can function as part of a statement, it does not require a return value like traditional functions do; it is more of a procedural output command rather than a function that returns a value.
