Explanation of C++ Code from Codegrepper.com

#include <iostream>
using namespace std;

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

1. Include Input/Output stream library: The #include <iostream> directive includes the Input/Output stream library, which provides functionality for input and output operations.

2. Using the standard namespace: The using namespace std; statement allows the program to access elements of the std namespace without needing to prefix them with std::.

3. Main function: The int main() function is the entry point of the program where the execution begins.

4. Output: The cout << "Hello, World!" << endl; statement outputs the text "Hello, World!" to the standard output stream, followed by a new line.

5. Return statement: The return 0; statement is used to indicate successful termination of the program. The value 0 is conventionally used to indicate successful execution.

This C++ program simply outputs "Hello, World!" to the console and then terminates.
