Program flowchart and system flowchart Programs are the collection of set of instruction which perform some certain activities. These interrelated programs are collectively called software or in general we call it information system. Information system is capable of processing raw data into information depending upon the users requirements. Thus, information system should process several types of data for several purpose or job which are done through programs. In short information system is a collection of programs. While developing a software, we design our software by using flowchart and other several designing tools. Flowchart is the diagrammatic or pictorial representation of steps involved while solving a problem. It illustrates the sequence of operations required to solve a problem. There are mainly two types of flowchart: Program flowchart and System flowchart. Program flowchart: It represents the steps involved in solving a particular problem. It illustrates the f...

What is OOPs? OOP stands for Object-Oriented Programming. It is a programming paradigm that focuses on the concept of objects, which are instances of classes that contain data and methods that operate on that data. OOP is based on the idea of modularity, which means that complex systems can be built from smaller, simpler pieces that can be easily maintained and extended. In OOP, objects are the building blocks of programs, and the design and implementation of the objects are based on the principles of encapsulation, abstraction, inheritance, and polymorphism. Encapsulation is the process of hiding the implementation details of an object and providing a public interface for accessing the object's data and methods. Abstraction is the process of defining the essential features of an object and ignoring the non-essential details. Inheritance is the process of creating new classes that inherit the properties and methods of existing classes. Polymorphism is the ability of objects of diff...
