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...

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 ·    ...
