This document introduces programming and visual basic. It defines programming as the study of computer languages. Visual Basic is described as a tool created by Microsoft to build user-friendly computer applications using a graphical user interface. It then defines key programming concepts like flowcharts, algorithms, operators, variables, loops, and provides examples of how they are used in programming with flowcharts and pseudocode.

- 1. Introduction to Programming What is programming ? It deal with the study of computer languages What is visual Basic? It a tool created by Microsoft to build a computer application in a user friendly environment Thesupport Graphical User Interface (GUI) Flowcharts - Agraphical representation of step bystep instructions to slove a problem . Algorithm – A set of step byinstruction to slove a problem . Operator – An engine used to perform logical Mathematical operations. Variable – Amemory storage /container Loop– An action that repeatedly and continuously perform until a certain condition is done.
