Write a C++ program that prints "Hello World!"
Here is a simple C++ program that prints "Hello World!" when you run it:

```cpp
#include <iostream> 

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

This program includes the `iostream` library, which provides the necessary tools for standard input and output in C++. The `main` function is where the code execution begins. Inside the `main` function, the `std::cout` statement is used to display the text "Hello, World!" on the screen. Finally, the `return 0` statement indicates successful program termination.
Below is an instruction that describes a task, write a response that appropriately completes the request.
