      Algorithm

      The term algorithm is used in a variety of fields, including mathematics, computer programming, and linguistics. Its most well-accepted definition is something that consists of a finite list of instructions (which are well defined) that can be used to accomplish a task. Basically, when an algorithm is given some initial state, it will use the

      Type Conversion – Class to Class

      Now that we have understood how to convert basic data types to class types and vice-versa, it is time to learn how to convert objects of one class type to another class type. The conversion between objects of different classes can be done using either a one-argument constructor or a conversion function. The choice depends

      How to Find Security Vulnerabilities in Source Code

      The original, and still the best, method for finding security vulnerabilities in source code is to read and understand the source code. Source code security vulnerabilities will vary between languages and platforms. Items to look for in C code include: Potential vulnerability Function calls to examine for vulnerabilities Buffer overflows gets(), scanf(), sprintf(), strcat(), strcpy()

    • Hex Editor

      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

      Java Servlet

      A Java Servlet is the Java technology used to extend and improve Web server functionality. Servlets are able to provide a platform independent way to build web-based applications founded upon components without the performance limitations found with comparable CGI applications. Since Java Servlets are platform and server independent, they can be deployed across the full
