Jump to Level 6 Level 6 Jump to Level 7 Level 7 Jump to Level 8 Level 8 Be a Code Ninja! If you are a C / C++ user, note that pointers and arrays go hand in hand. So, we will spend some time covering the basics of pointer. ...
This can be a little confusing. Functions that return pointers almost always return a valid pointer (one that doesn't compare equal to zero) on success, and a null pointer (one that compares equal to zero) pointer on failure. Other functions return an int to show success or failure; typic...
1) References are less powerful than pointers. Once a reference is created, it can't refer to other object later.1) Pointers provide the powerful facilities than references. 2) References are safer and easier to use than pointers.2) Pointers are comparatively difficult to use. ...
Further you can go through your past assignments you have done with the subject and make sure you are able to speak confidently on them. If you are fresher then interviewer does not expect you will answer very complex questions, rather you have to make your basics concepts very strong. ...

Declare two pointers, first and second, which are initialized to the linked list head. Increment the first linked list by two nodes and the second by one node in each loop. While the first node reaches the end of the list, the second node will point to the middle. ...
Below-mentioned is the differentiating pointers based on which Node Js and Django differ from each other- Node.Js Django Node.Js is a type of open-source framework based on JavaScript which is used to develop web applications. Django is a type of open-source framework based on Python which ...
Inserting: Once you have located the position where you want to insert, you will adjust the pointers in a way such that your previous node which is the node containing 5, will have the next pointer pointing to the new node containing 6.You then need to point the next pointer of your ne...

The delegates in .NET are like the pointers to the functions in C/C++. The difference is that these are type safe unlike the once in C/C++. There are situations where in a programmer or an application needs to perform an action on a particular event. Eg: Some user action like click,...
