Programming involves studying computer languages like Visual Basic, which was created by Microsoft for building graphical user interface applications. Key concepts include graphical user interfaces, flowcharts representing step-by-step problem solving instructions, algorithms as sets of steps, and operators for logical and mathematical operations. Variables store values and loops repeatedly perform actions until a condition is met. Examples demonstrate arithmetic, relational, and logical operators as well as using variables, conditions, and flowcharts in algorithms.

Introduction to programming
- 1. Introduction to Programming What is programming? Programming – deals with the study of computer language. What is a Visual Basic? Visual Basic – is too created by Microsoft to build a computer application in a user-friendly environment that supports Graphical User Interface. GUI – Graphical User Interface Flowchar – A graphical representation of step by step instruction 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 operaters + Addition - subtraction * Multiplication / Division 2. Relational operaters > greater than < less than >= greater than or equal to <= less than or equal to ===or==or= equal to <>or= not equal to
