Programming involves the study of computer languages like Visual Basic which is a tool created by Microsoft to build applications with a graphical user interface. Key concepts in programming include flowcharts which graphically represent step-by-step instructions to solve problems, algorithms which are sets of instructions to solve problems, variables which are containers for storing memory, and loops which repeatedly perform actions until a condition is met. Operators perform logical and mathematical functions in programming.

1. IntroductiontoProgramming
What isprogramming?
Programming– deal withthe studyof computerlanguage.
What isa Visual Basic?
Visual Basic(Vb) –is a tool createdby Microsoftto buildacomputerapplicationinauser-friendly
environmentthatsupportsGraphical UserInterface.
GUI – Graphical User Interface.
Flowchart– A graphical representationof stepbystepinstructionstosolve aproblem.
Algorithm–A setof stepby stepinstructiontosolve aproblem.
Operator– Anengine usedtoperformlogical andmathematical operations.
Variable –A memorystorage / container.
Loop – An actionthat repeatedlyandcontinuouslyperformuntilacertainconditionisdone.
Operators:
1.)Arithmeticoperators
+  Addition
-  Subtraction
*  Multplication
/  Division
2.)Relational operator
>  greaterthen
<  lessthan
>=  greaterthan or equal to
<=  lessthanor equal to
===or==or=  equal to
<>or!=  not equal to

2. 3.)Logical operator
||  OR
&&  AND

preparation Ex. X= 5, y = 6Z x +z Print …?
Collect materials
Variable : x,y
Z = x + y
Is Z less than 100? Yes
or No
Is … ? less than 100?
