include

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

Explanation:

1. The first line "#include " is a preprocessor directive that tells the compiler to include the iostream library. This library provides classes and functions for input and output operations.

2. The "int main()" line is the main function of the program. It is the entry point for the execution of the program.

3. The "{ }" curly braces enclose the body of the main function. All the statements within these braces will be executed when the program runs.

4. The "std::cout" is an object of the std namespace that represents the standard output stream. It is used to display output on the console.

5. The "<<" operator is the insertion operator, which is used to insert data into the output stream.

6. "Hello, World!" is the string that we want to display as output.

7. The semicolon ";" at the end of the line marks the end of the statement.

8. The "return 0;" statement is used to indicate the successful completion of the program. The value 0 is returned to the operating system.

Overall, this program simply prints the message "Hello, World!" to the console.
