</div>
<script src="js/angular-1.3.0.js"></script>
<script>
/*

$scope.greeting = { text:"Hello" }
$rootScope.program = { text:"angularjs" };
}
function Ctrl2($scope){
$scope.greeting = {text:"Good morning"};
}
*/
var app = angular.module("myApp", []);
app.controller("Ctrl1", function($scope, $rootScope){
