This document introduces some basic concepts of programming including Visual Basic, flowcharts, algorithms, operators, variables, and loops. It defines Visual Basic as a tool created by Microsoft for building graphical user interface applications. It also defines flowcharts as graphical representations of problem-solving steps, algorithms as sets of instructions, operators as tools for logical and mathematical operations, variables as memory containers, and loops as repetitive actions. Finally, it provides examples of arithmetic, relational, and logical operators, and demonstrates a simple flowchart algorithm using variables.

1. Introduction to Programming
What is programming ?
Programming – deals with the study of company language
What is a VisualBasic ?
VisualBasic (VB) – is a tool created by Microsoftto build a computer application
in a user-friendly environmentthat supports GraphicalUser 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 solvea problem.
Operator – An engine used to perform logical and mathematical operations.
Variable – A memory storage/container
Loop – An action that repeatedly and continuously performuntil a certain
condition is done.

2. Operator :
1.)Arithmetic operators
+  addition
-  Subtraction
*  Multiplication
/  Division
2.)Relational Operator
>  Greater than
< Less than
>= Greater than or equal to
<=  Less than or equal to
===or==or= Equalto
<>or!=  Not equal to
3.)LogicalOperators
|| OR
||
&& AND

3. Flowchart Algorithm Variables
Preparation Ex : 1.)
X = 5 x = 5
CollectMaterialsVariable:X ,Y y = 4 y = 4
Z = X+Y Z = X+Y Z = X+Y
Condition
Is Z lessthan100 ? Yes or No Print ? Is ? lessthan100 ?
Yesor No
If true , re-startthe operation If true , restart
Else if false the operationElse if
