This document introduces some basic concepts in programming including Visual Basic, flowcharts, algorithms, operators, variables, and loops. It defines Visual Basic as a tool created by Microsoft for building graphical user interface applications. It also defines flowcharts as representing step-by-step instructions to solve a problem, and algorithms as sets of instructions to solve problems. Common operators, variables, and loops are outlined, with examples provided of arithmetic, relational, and logical operators. A sample flowchart and algorithm are given to demonstrate how these concepts are applied.

1. IntroductiontoProgramming
What isprogramming
Programming– dealswiththe studyof computerlanguage
What isa Visual Basic?
Visual Basic(vb) – isa tool createdbyMicrosoftto builda computerapplicationinauser-friendly
environmentthatsupportsGraphical UserInterface
GUI – Graphical User Interface
Flowchart– A graphical representationof stepinstructionstosolve aproblem.
Algorithm–A setoff stepbystepinstructiontosolve aproblem.
Operator– Anerqine usedtoperformlogical andmathematical operations.
Variable –A memorystorage /container.
Loop – An actionthat repeatedlyandcontinuouslyperformuntilacertainconditionisdone.
Operators:
1) Arithmeticoperators
+  Addition
-  Subtraction
* Multipication
/  Division
2) Relational Operatior
>greaterthan
< lessthan
>= greaterthanor equal to
<= lessthanor equal to
===or==or=  equal to
<>or!= notequal to
3) Logical operators
|| OR &&  AND
