This document introduces some basic concepts of programming including Visual Basic, flowcharts, algorithms, variables, operators, and loops. It defines Visual Basic as a tool created by Microsoft for building graphical user interface applications. It also defines flowcharts as graphical representations of step-by-step instructions to solve a problem, and algorithms as sets of step-by-step instructions. Operators are used to perform logical and mathematical operations on variables, which are memory containers. Loops repeatedly perform an action until a certain condition is met.

Algorithem- A setof stepby step instructiontosolve aproblem.
Operator– Anengine usedtoperformlogical andmathematical operations.
Variable –A memorystorage/container.
Loop – An actionthat repeatedlyandcontinuouslyperformuntilacertainconditionisdone.
Operatoes:
1)Arithmeticoperators
+  addition
-  Subtraction
* Multiplication
/  Division
2)Relational Operatior
>  greaterthan
<  lessthan
>=  greaterthan or equal to
<=  lessthanoe equal to
=== or == or =  equal to
<> or !=  not equal to
3)Logical operators
||  Or
&&  and
