. The cout with the insertion operator (<<) is used to print a statement

The cout object in C++ is used to display output on the console. It is part of the iostream library and is used in conjunction with the insertion operator (<<) to print statements.

Here is an explanation of each step involved in using cout with the insertion operator:

1. Including the necessary header file: To use cout, you need to include the iostream header file at the beginning of your program. This is done using the #include preprocessor directive: cpp #include <iostream>

2. Using the cout object: Once the iostream header file is included, you can use the cout object to display output on the console. This is done by using the cout object followed by the insertion operator (<<): cpp std::cout << "Hello, world!";

3. Inserting the content: After the cout object, you need to provide the content that you want to display. This can be a string literal, a variable, or an expression. In the example above, the string "Hello, world!" is being displayed.

4. Ending the statement: The statement using cout and the insertion operator needs to be terminated with a semicolon (;). This tells the compiler that the statement is complete.

Here is an example that puts all the steps together:

#include <iostream>

int main() {
   std::cout << "Hello, world!";
   return 0;
}

This program will display the text "Hello, world!" on the console when executed.
