ALGORITHM• Produce an ordered sequence of steps
that describe solution of problem• This sequence of steps is called an Algorithm
• Set of instructions that leads to a predictable result
• Goal is to create efficient Algorithms that do not waste more computer resources and time than necessary
Flowchart
• A graphical representation of the sequence of operations in an information system or program
• Shows logic of an algorithm• Emphasizes individual steps and their
interconnections• Different symbols are used to draw each
type of flowchart.• Used in analyzing ,designing and
documenting complex process or programs
Flowchart symbols
Oval
Parallelogram
Rectangle
Diamond
Hybrid
Name Symbol Use in Flowchart
