This document provides an introduction to programming concepts. It defines programming as dealing with computer languages and visual basic as a tool created by Microsoft for building graphical user interface applications. It discusses flowcharts as a graphical representation of step-by-step instructions to solve a problem and algorithms as a set of instructions to solve a problem. It also defines operators, variables, loops and provides examples of arithmetic, relational and logical operators. Finally, it demonstrates a flowchart algorithm for adding two variables and checking if the result is less than 100.

- 1. Introduction to Programming What is Programming ? Programming – deals with the study of computer language What is a Visual Basic ? Visual Basic (Vb) – is a tool created by Microsoft to build a computer application in a user- friendly environment that supports Graphical User 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 solve a problem. Operator – An enqine used to perform logical and mathematical operation. Variable – A memory storage / container. Loop – An action that repeatedly and continuously perform until a certain condition is done. Operators : 1.) Arithmetic operators + Addition - Subtraction * Multiplication / Division 2.)Relational Operators > greater than <less than >=greater than or equal to <=less than or equal to ===or==or= equal to
