C++ Hello, world!

Hello, world! is often the first program that we write in a new programming language. It helps us to understand the most basic application syntax and is a good way to test our tool chain to make sure that we can compile and/or run a program.

// Simple first program.

#include <iostream>
#include <string>

using namespace std;

int main(int argc, char **argv) {
	cout << "Hello, world!" << endl;
	return 0;
