	// Assigning variable:
	// + variable may get value only after declared
	// + type of value must match type of variable
	// + value persists until {} ends!
	
	// Syntax:
	// type var; (declare)
	// var = expr; (assign)
	// Shortcut: type var = expr;

	// Language:
	   int x;
           x = 1;           // shortcut: _______
        // Assign 1 to $x$
	// $x$ gets 1
        // x<-1 (pseudocode)

	// Variable keeps value until $main$ ends
	   System.out.println("Current value of x: "+x);
	
	// Can reassign value:
	   x = 2;
	   System.out.println("Current value of x: "+x);

	// Variable must have value before you use it!
	   int test;
	   // System.out.println(test);
