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.Algorithun – A set of step by step instruction to solve a problem.Operator – An enqine used to perform logical and mathematical operations.Variable – A memory storage/containerLoop – An action that repeatedly and continuously perform until a certain condition is done.

Preparation ex: 1.) ex: 2.) x=5 x=5 collect materials x=6 x=6 Variable : x,y z = x+y z = x+y Condition : Z = x+y Print ? 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
