    • Doubly Linked List

      Doubly Linked List

      In a doubly linked list, also called a two-way list, each node is divided into three parts: The first part, called the previous pointer field, contains the address of the preceding element in the list. The second part contains the information of the list. The third part, called the next pointer field, contains the address

      Type Conversion – Class to Basic Type

      The constructor handles the task of converting basic types to class types very well. But you cannot use constructors for converting class types to basic data types. Instead, you can define an overloaded casting operator that can be used to convert a class data type into a basic data type. The general form of an

    • Disassembler


      A disassembler is a software that is able to convert an executable language into an assembly language, allowing users to view the individual commands that make a program work. A disassembler is ideal for programming applications because it can be useful when a programmer is attempting to create a similar program to one he/she already

    • Java Data Types

      Java Data Types

      Data types in the Java programming language are basically divided into two groups – primitive data types and object references. A primitive data type is a basic building block and has full built-in support. Many other languages also support composite data types, which are build on a combination of primitive data types and may or

    • Integer Overflow

      Integer Overflow

      An integer overflow, or integer wrapping, is a potential problem in a program based upon the fact that the value that can be held in a numeric datatype is limited by the data type’s size in bytes. ANSI C uses the following minimum sizes: data type size (bytes) char 1 short 2 int 2 long

This is most-often found within web pages with dynamic content. There are some excellent tutorials and descriptive articles on this subject, as well as many vulnerability postings for different applications from full-disclosure websites.

    • Deleting an Element from a Linear Linked List

      Deleting an Element from a Linear Linked List

      To delete an element from the list, first the pointers are set properly and then the memory occupied by the node to be deleted is deallocated (freed). This tutorial covers the deletion of a node from the following three positions: At the beginning of the list At the end of the list After a given
