c++hello world代码

Certainly! Here's a simple "Hello, World!" program in C++:

cpp
#include <iostream>

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

This program uses the iostream header for input and output operations. The main function is the entry point of the program, and std::cout is used to print the "Hello, World!" message to the console. Finally, return 0; indicates that the program has executed successfully.
