How to use apex:inputText in Visualforce Page?

How to use <apex:inputText>  in Visualforce Page?

<apex:inputText> :

An HTML input element of type text. Use this component to get user input for a controller method that does not correspond to a field on a Salesforce object.

This component does not use Salesforce styling. Also, since it does not correspond to a field, or any other data on an object, custom code is required to use the value the user inputs.


Syntax:
<apex:inputText value="{!inputValue}" id="theTextInput"/>
