Q:

AngularJS beginner: ng-controller not working

I'm just trying to get my head around the basics of AngularJS.  I tried writing a simple MVC app, but the controller doesn't seem to be working.  The file can find the angular lib just find, I already tested that by excluding 'ng-controller'. 
<!DOCTYPE html>
<html ng-app>
<head>
    <script src='js/lib/angular.js'></script>
    <script>
        // controller
        function MyFirstCtrl($scope) {
            // model
            var employees = ['Christopher Grant', 'Monica Grant', 'Christopher
            Grant', 'Jennifer Grant'];

            $scope.ourEmployees = employees;
        }
    </script>
</head>
<body ng-controller='MyFirstCtrl'>
    <!-- view -->
    <h2>Number of employees: {{ourEmployees.length}}</h2>
</body>
</html>

EDIT:
The error log says the following:
Uncaught SyntaxError: Unexpected token ILLEGAL , line 9
Uncaught SyntaxError: Unexpected token { , line 19
Error: [ng:areq] Argument 'MyFirstCtrl' is not a function, got undefined

EDIT2: I changed the code to this:
<!DOCTYPE html>
<html ng-app='MVCExample'>
<head>
    <script src='js/lib/angular.js'></script>
    <script>
        var app = angular.module('MVCExample', []);

        // controller
        app.controller("MyFirstCtrl", function($scope) {

            // model
            var employees = ['Christopher Grant', 'Monica Grant', 'Christopher Grant', 'Jennifer Grant'];

            $scope.ourEmployees = employees;
        });
    </script>
</head>
<body ng-controller='MyFirstCtrl'>
    <!-- view -->
    <h2>Number of employees: {{ourEmployees.length}}</h2>
</body>
</html>

It also turned out that the 'employees' array that I had was illegal since I had one string entry split into two lines.  The above works.  The beginner book I am using must be outdated, which is unfortunate. 

A:

If you're using angularjs 1.3+ versions then you can not declare global controller like above you're doing. 
You should initialize like below.
<div ng-app="appname" ng-controller="MyFirstCtrl">
var app = angular.module('appname', []);
app.controller('MyFirstCtrl',function(){
   //controller code here
});
