Visual Basic is a programming tool created by Microsoft that allows users to build graphical user interface applications in an easy-to-use environment. Programming involves studying computer languages and deals with flowcharts, algorithms, operators, variables, and loops. Flowcharts provide a graphical representation of step-by-step instructions to solve a problem while algorithms are sets of instructions. Operators perform logical and mathematical operations on variables, which are memory containers. Loops repeatedly perform an action until a condition is met.

1. Introduction to programming
What is programming?
Programming-deals with the study of computer language
What is visual Basic?
Visual Basic(vb)-is a toolcreated
ByMicrosoft 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 setof step by step instruction to solve a problem
Operator-An engine used to perform logical andmathematical operation
Variable-A memory storage /container
Loop-An action thatrepeatedly and continuously perform until a certain condition is done
Operators:
1)Arithmetic operators
+addition
-Subtraction
*multiplication
/division

2. 2)Relational operatior
>greater than
<less than
>=greater than or equal to
<=greater than or equal to
===or==or=equalto
<>or!=not equalto

Preparation
Collect materials variable:X,Y
Z=X+Y
Is Z less than 100? Yes or No
If true,re-start the operation Else if falseDisplay result Then Endoperation
Variables
EX1)
X=5
Y=6
Z=X+Y
