Even these attributes and methods of objects are themselves objects with their own type information. Every object can be assigned to a variable or…

Object Oriented Programming is not a programming language, but rather a model in which programs are organized around data or objects. OOP uses the concept of objects and classes. A class can be thought of as a ‘blueprint’ for objects. These can have their own attributes (characteristics), and methods (actions…

What are libraries and why use libraries in c ? A library is a file containing several object files, that can be used as a single entity in a linking phase of a program. Normally the library is indexed, so it is easy to find symbols (functions, variables and so on) in them. For this reason, linking a program whose…

ls is one of the most common commands in a Linux shell and probably the first command that you would use when learning Linux. Let’s take a look at what ls does when we enter it in a shell: As you can see it prints all available files and folders…

Computer machines are composed by digital memories that store information in bits (binary digit). It means that a bit is an unit — the smallest one — used to quantify computer data . The bit represents a logical value, which corresponds to a two-state device. These states are often represented…
