The possibilities which may arise during deleting a node from a binary tree are as follows: Node is a terminal node: In this case, if the node is a left child of its parent, then the left pointer of its parent is set to NULL. Otherwise if the node is a right child of its …
To understand what a format string vulnerability is, you first need to know what a format string is. A format string is a way of telling the C compiler how it should format numbers when it prints them. Format Strings in C In the C programming language there are a number of functions which accept …
JavaScript is the most widely used client-side scripting language. Almost all websites these days make use of JavaScript directly or via 3rd-party frameworks like JQuery, Prototype, Bootstrap, MooTools, YahooGUI, etc. JavaScript is mostly used for advance web functionality like validations, animation, Ajax-based calling, making flexible interfaces, etc. Therefore, it is important to make sure that …
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 …
The ability to debug any modern programming language is a critical skill for programmers of all skill levels. Learning how to debug Java helps developers discover the causes of logic and non-trivial syntax errors that prevent proper execution of Java programs. The ability to step-through a Java program using a debugging environment provided by updated …
Java and JavaScript are two different programming languages meant for different purposes and functionality. Java is an application programming language designed to write stand-alone Java programs and web applications running on the Internet. JavaScript is a client-side scripting language specifically designed to work with various web technologies, but on the client’s end. To understand the …
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 …
Computer users sometimes need to uninstall Java, for various reasons. In case of upgrading Java, you needn’t remove the previous version of Java. Instead, you can simply run the executable of the newer Java version and the upgrade will automatically happen. However if you wish to uninstall Java, below are the methods for different platforms. …
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 …
PLC (Programmable Logic Controller) programming allows a computer to automate mechanical or electrical processes for machinery, lighting, or assembly line control actions. Over the past two decades, PLC programming has been used in a number of industries. The PLC’s design allows it to take multiple inputs and provide various outputs. A PLC device is also …
