#include <iostream>
using namespace std;

int main()
{
	int num1 = 1;	// this statement declares AND initializes num1
	int num2, num3; // this statement only declares num2 & num3. While the use
                    	//    of the comma is syntactically legal, I prefer that 
                    	//    student's declare separate variables with
			//    separate declaration statements.

	num2 = 400;	// assigning 400 to num2 with an assignment statement. 
			// 	This is NOT a declaration or initialization statement.

	num3 = num2;			// assigning value of num2 to num3
	num1 = num2 + 3 * num3;		// C++ evaluates the multiplication before the addition

	cout << "num1 = " << num1 << endl;
	// the line above prints "num1 = 1600"

	cout << "num2 = " << num1 * 2 << endl;

	// the line above prints "num2 = 3200" but does not
	// actually change the assigned value of num2 to 3200

	cout << "num2 = " << num2 << endl;
	// the line above prints "num2 = 400"

	return 0;
}// end of main
