Visual Basic is a programming tool created by Microsoft to build graphical user interface (GUI) applications in a user-friendly environment. It supports key programming concepts like flowcharts, algorithms, variables, loops, and operators. Flowcharts provide a graphical representation of step-by-step instructions to solve a problem. Algorithms are sets of step-by-step instructions to solve a problem. Variables act as containers to store and memory values. Loops allow actions to be performed repeatedly until a condition is met. Operators include arithmetic, relational, and logical operators to perform math operations and make comparisons.

Input Collect Materials variable : X,Y
Is ?lesthan 100 ?
yesor no
Process Z = X+Y
If true thenre-startthe
operation
Condition Is z less than 100?yes or no Eke this false display
Output If true re-start the operation
Else if false Display result
End Then End operation Thenendthe operation
