Visual Basic is a programming tool created by Microsoft to build graphical user interface applications in a user-friendly environment. Programming involves studying computer languages. A flowchart uses graphics to represent step-by-step instructions to solve a problem while an algorithm is a set of instructions. Operators perform logical and mathematical operations on variables, which are memory containers. Loops repeatedly perform an action until a condition is met. Common operators include arithmetic, relational, and logical operators. Flowcharts and algorithms use variables, conditions, and logic to represent the preparation, processing, and output of a program.

- 1. Introduction to Programming What is Programming ? Programming –deals with the study of computer language Whatis 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 graphicalrepresentation of step by step instructions to solve a problem. Algorithun –A setof step by step instruction to solve a problem. Operator – An enqine used to perform logical and mathematical operations. Variable –A memory storage/container Loop– An action that repeatedly and continuously perform until a certain condition is done.

Is? less than 100% Yes or No If true, then re-start The operation Is Z less than100? Else is fales Yes or No Display ? Then End the Operation If true, re-sport the Operation Else is false Display result Then End operation Start INPUT Process Condition Out put END
