What is the need of “Custom Controller” in Visualforce as everything can be done by the combination of Standard Controller + Extension class.
Ans :

Sharing setting is applied on standard object/extension by default; In case we don’t want to apply sharing setting in our code then Custom controller is only option.

It is possible that the functionality of page does not required any Standard object or may require more than one standard object, then in that case Custom controller is required.

n class declaration if we don’t write keyword “with sharing” then it runs in system mode then why keyword “without sharing” is introduced in apex?
Ans:

Lets take example, there is classA declared using “with sharing” and it calls classB method. classB is not declared with any keyword then by default “with sharing” will be applied to that class because originating call is done through classA. To avoid this we have to explicitly define classB with keyword “without sharing”.
