// Purpose - to illustrate the use of the for loop

#include <iostream>
using namespace std;

int main()
{
	int loopCounter = 0;  // loop variable

	for (loopCounter = 1; loopCounter <= 10; loopCounter++)
	{
		cout << loopCounter << endl;
	}

	// The values 1 through and including 10 are displayed.
	// Notice the use of blank lines above and below the for loop for readability.

	for (loopCounter = 1; loopCounter < 10; loopCounter++)
	{
		cout << loopCounter << endl;
	}

	// The values 1 through and including 9 are displayed BUT
	// loopCounter's final value is 10. Can you explain why?

	for (int loop = 0; loop != 10; loop++)
	{
		cout << loop << endl;
	}

	// The loop variable loop is declared and initialized to the
	// starting value of 0 within the initializing expression
	// of the for loop. The control expression loop != 10 is very
	// dangerous here. The loop does stop iterating when loop
	// increments to the value of 10 but if, for whatever reason,
	// loop "skipped over" the value of 10, the loop would iterate
	// forever. In that case, the for loop would be an infinite 
	// loop and the C++ program would never stop executing!
	// Does the value of 10 print in this loop?

	return 0;
}// end of main
