#include <iostream.h> //Required header file for i/o streams

extern void ask_question(void); // Here is the use of extern. The extern keyword simply tells the program that the actual
								// declaration of the function ask_question is located somewhere else, and to use that declaration when 
								// the function ask_question is called from anywhere in this file. However, extern also has scope, just like
								// any other declaration in C++. If you were to move this line to after the { in the function
								// main, the program would only be able to call ask_question from inside the main function.

int main() // The main function. This is where the program starts
{
	cout << "Hello world!" << endl; // Output a hello statement
	ask_question(); // Call the function called ask_question.
	return(0);
