This document introduces some basic concepts of programming including Visual Basic, flowcharts, algorithms, operators, variables, and loops. It defines Visual Basic as a tool created by Microsoft for building graphical user interface applications. It also defines flowcharts as graphical representations of problem-solving steps, algorithms as sets of instructions, operators as tools for logical and mathematical operations, variables as memory containers, and loops as repetitive actions. Finally, it provides examples of arithmetic, relational, and logical operators, and demonstrates a simple flowchart algorithm using variables.

Introduction to programming
- 1. Introduction to Programming What is programming ? Programming – deals with the study of company language What is a VisualBasic ? VisualBasic (VB) – is a tool created by Microsoftto build a computer application in a user-friendly environmentthat supports GraphicalUser Interface GUI – Graphical User Interface Flowchart– A graphical representation of step by step instructions to solve a problem. Algorithm – A set of step by step instruction to solvea problem. Operator – An engine used to perform logical and mathematical operations. Variable – A memory storage/container Loop – An action that repeatedly and continuously performuntil a certain condition is done.
- 2. Operator : 1.)Arithmetic operators + addition - Subtraction * Multiplication / Division 2.)Relational Operator > Greater than < Less than >= Greater than or equal to <= Less than or equal to ===or==or= Equalto <>or!= Not equal to 3.)LogicalOperators || OR || && AND
- 3. Flowchart Algorithm Variables Preparation Ex : 1.) X = 5 x = 5 CollectMaterialsVariable:X ,Y y = 4 y = 4 Z = X+Y Z = X+Y Z = X+Y Condition Is Z lessthan100 ? Yes or No Print ? Is ? lessthan100 ? Yesor No If true , re-startthe operation If true , restart Else if false the operationElse if false Display result Display ? Then Endoperation ThenEnd operation Start input Process Condition Output End
