This document provides an introduction to programming concepts. It defines programming as dealing with computer languages and visual basic as a tool created by Microsoft to build graphical user interface applications. It discusses flowcharts as graphical representations of step-by-step instructions to solve problems, algorithms as sets of instructions to solve problems, and operators, variables, loops, and common operators used in programming like arithmetic, relational, and logical operators.

1. Introduction to programming
What is programming?
Programming - deals with the study of computerlanguage
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.
Algorithan – A set of step by step instruction to solve a problem.
Operator– An engine used to perform logical and Mathematical operations.
Variable – Amemory storage / container
Loop – An action that repeatedly andcontinuously perform until a certain
condition is done.

2. Operators
1) Arithmetic operators
+ ➸ Addition
- ➸ Subtraction
* ➸ Multiplication
/ ➸ Division
2) Relational operator
> ➸ greater than
< ➸ less than
>= ➸ greaterthan or equalto
<= ➸ less than or equalto
===or==or= ➸ equalto
<>or!= ➸ not equalto
3) Logical operators
|| ➸ OR

3. && ➸ AND

Preparation
Collertion of the thing
need Variable X,Y
Z=X+Y
Is Z less than yes or no
If yes then repeat the
input Else if no Display
Result
End the operation
Ex) X=5 Ex:2
X=5 X=6 Y=6 Z=x+y
Z=x+y Condition
Print____Is__less then
100 yes or no If true
then repeatthe
operation Else if false
Display____
Then End the operation
