How to Insert Standard List Controller in Visualforce page?

As a Salesforce developer, we must have good knowledge on Salesforce Apex programming and about Visualforce pages. Now will understand how to add Standard List controller in visualforce page. StandardController attribute must be used in <apex:page> component and then we use recordSetVar attribute on the same component. This recordSetVar attribute indicates that the page uses a list controller and variable name(used to access data) of the record collection.

So what happens when recordSetVar attribute is added.

<apex:page standardController="Tutorial__c" recordSetVar="tutorial" 
tabStyle="account" sidebar="false">

As shown above, the variable name for the list is the value of recordSetVar, in this instance accounts. Next at runtime the query will not use an id, but will default to the last used List View the user has used.
