here's an example of a simple "Hello, World!" program in C++:

#include <iostream>

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

This program uses the iostream library to print the message "Hello, World!" to the console. The int main() function is the entry point of the program, and the return 0 statement indicates that the program has completed successfully.

To run this program, you would need to save it in a file with a .cpp extension (e.g., hello.cpp), compile it using a C++ compiler (such as g++ on Linux or macOS, or Visual C++ on Windows), and then run the resulting executable file (e.g., hello.exe on Windows, or ./hello on Linux or macOS).
