How do I output a string in C++ programming?
You can output strings in many ways one of the simplest methods is :
```cout << string```
Can you extend the example so that I can copy it into a text file and run it?
Sure, here's an example:
```
#include <iostream>
#include <string>

int main() {
  std::string str = Hello, World!;
  std::cout << str << std::endl;
  return 0;
}
```
Save the code to a file with a `.cpp` extension, then compile and run it using a C++ compiler.
