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.

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

2. 3. logical operaters
!! or
&& and
Flowchart Algorithm
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 False
Then End operation

3. 4.Variable
4.1 x = 5
y = 6
z= x+y
print = ?
4.2 x = 5
y = 6
z= x+y
print = ?
condition :
Is ____ less than 100?
Yes or No
If true , then restart the operaters Else if fals
Display ________
Then End the operation
