      Binary Tree – Searching a Node

      An element in a binary search tree can be searched very quickly. A search operation on binary tree is similar to applying binary search technique to a sorted linear array. The element to be searched will be first compared with root node. If it matches with the root node then the search terminates. Otherwise search

    • Overloading Binary Operators

      Overloading Binary Operators

      Binary operators can be overloaded in a similar manner as unary operators. We should note the following features of an operator function for a binary operator: It receives only one class type argument explicitly, in case of a member function. For a friend function, two class types are received as arguments. It returns a class

      javascript:void(0)

      The javascript:void(0) error is fairly unique, in that it  is one of the few computer-based errors that can be encountered by users of any operating system. The error is thrown on web browsers with the end-user surfs to websites that are not fully compatible with the version of Internet browser being used or have a

      Java Package

      A Java package is a set of classes which are grouped together. This grouping helps to organize Java classes and codevent multiple Java classes with the same name. Using Java Packages To use a package in your Java source code, you must either import the package or use the fully qualified class name each time

    • Constructors in Derived Classes

      A constructor plays a vital role in initializing an object. An important note, while using constructors during inheritance, is that, as long as a base class constructor does not take any arguments, the derived class need not have a constructor function. However, if a base class contains a constructor with one or more arguments, then

    • Exception Handling

      Exception Handling

      There are two kinds of exceptions, namely, synchronous exceptions and asynchronous exceptions. Errors such as “out-of-range index” and “over-flow” belong to the synchronous type exceptions. The errors that are caused by events beyond the control of the program (such as keyboard interrupts) are called asynchronous exceptions. The proposed exception handling mechanism in C++ is designed

    • Deleting an Element from a Heap

      Deleting an Element from a Heap

      Deleting an Element from the Heap Deletion always occurs at the root of the heap. If we delete the root element it creates a hole or vacant space at the root position. Because the heap must be complete, we fill the hole with the last element of the heap. Although the heap becomes complete, i.e.

      Hex Editor

      A hex editor is a program edits compiled programs and binary data files. These editors are called hex editors because they most often present data in hexadecimal format. Hexadecimal is used because it is easier for most humans than working in binary. In addition, hexadecimal is frequently useful because computers tend to work with 8-bit
