C++ Lec-2 Introduction to Object-Oriented Programming (OOP) in C++

  Introduction to Object-Oriented Programming (OOP) in C++ Object-Oriented Programming (OOP) is a programming paradigm that uses objects and classes to organize software design. It allows for modelling real-world entities and relationships in a program. C++ is an object-oriented programming language that provides features to implement OOP concepts effectively. Key Concepts of OOP   Class and Object o    Class : A blueprint for creating objects. It defines properties and behaviours of objects.   class Car { public:     string brand;     string model;     int year; };   o    Object : An instance of a class.   Car car1; car1.brand = "Mahindra"; car1.model = "THAR"; car1.year = 2024;   Encapsulation o    Encapsulation is the bundling of data and methods that operate on that data within a single unit, or class. It restricts direct acces...

C++ Lec-1 (Introduction to Programming Languages)

  Introduction to Programming Languages ________________________________________________________________________ P rogramming languages are formal languages comprising a set of instructions that produce various kinds of output. They are used in computer programming to implement algorithms and control the behavior of machines. Language Generation Programming languages have evolved through several generations: First Generation (1GL) : Machine language, the most basic level of programming languages, consisting of binary code. Second Generation (2GL) : Assembly language, a low-level language with a strong correspondence to the machine language instructions. Third Generation (3GL) : High-level languages like C, C++, Java, Python, which are more abstract and easier for humans to understand. Fourth Generation (4GL) : Languages closer to human language, often used for database querying and report generation (e.g., ...

Flow Charts - What Is a Flow Chart? When to Use a Flowchart? Flowchart Symbols & Components

  Flow Charts     Flow charts are a useful tool in many situations, as we make a process easy to understand at a glance. Using just a few words and some simple symbols, they show clearly what happens at each stage and how this affects other decisions and actions.   What Is a Flow Chart?     In 1921, the Frank and Lillian presented what was only a "graphic-based method" in a presentation titled: “ Process Charts: First Steps in Finding the One Best Way to do Work ”, to members of the American Society of Mechanical Engineers (ASME). When to Use a Flowchart?     Flowchart is a very simple yet powerful tool to improve productivity in both our personal and work life. Here are some ways flowchart can be helpful:   ·      Document a process ·      Present solution to a problem ·      Brainstorm ideas in a meeting ·      Design an operation system ·    ...
