Programming involves studying computer languages. Visual Basic is a tool created by Microsoft to build graphical user interface (GUI) applications easily. Flowcharts graphically represent step-by-step problem solving instructions using variables, operators, and loops. Operators perform logical and mathematical operations. Variables store values. Loops repeatedly perform actions until a condition is met. Flowcharts, algorithms, and variables are used with relational and logical operators to solve problems through programming.

1. 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.
Algorithm – A set of step by step instructions to solve a problem.
Operator – An engine 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.
Operators:
1.) Arithmetic operator
+ Addition
- Subtraction
* Multiplication
/ Division
2.) Relational Operator
> greater than
< lessthan
>= greater than or equal to
<= greater than or equal to
=== or == or = equal to
< > or != not equal to
3.) Logical Operators
|| OR
&& AND

2. Flowchart Algorithm Variables
preparation Ex. 1.) X = 5
y= 6
Z= x + y
Collect materials
Variable : X,Y
Ex. 2.) X = 5
y=6
Z= x + y
Z = X+Y
Print……? Is ….? Less than 100?
Yes or no
Is Z less than 100?
YES or NO If true, then re- short The operation
Else if false
If true, re-start the operation
Else if false
Display result Display…..?
Then end operation
Then End the operation
START
INPUT
PROCESS
CONDITION
OUTPUT
END
