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.

2. Operators:
1)Arithmetic operators
+ Addition
- Subtraction
* Multiplication]
/ Division
2.) Relational Operatior
> greater than
< Less than
>= greater than or equal to
<= less than or equalto’
===or==or= equalto
<>or!= notequal to
3.) Logicaloperators
||
OR
||
&& AND

3. Flowchart Algorithm Variables
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
Start
INPUT
Process
Condition
Out put
