flowchart as an algorithm?
an algorithm is expressed as a flowchart and then the flowchart is converted into a program with the programming language
what is a flowchart?
a type of diagram that represents an algorithm, workflow or process.
what are the benefits of flowchart.
effective analysis
visual clarity
problem solving
what are the types of flowcharts?
program flowcharts
system flowcharts
describe program flowcharts
- used by programmers
- shows the program structure, logic flow and operations performed.
- forms an important part of the system.
what does program flowchart include?
- program structure
- program logic
- data inputs
- data processing
- computations and calculations
- conditions
- branching and looping sequences
- results
- various outputs
describe system flowchart
- used by system analysts
- shows the various processes,sub systems outputs and operations on data in a system.
how to flowchart?
- use symbols or boxes of different shapes to denote different types of instructions.
- the instruction is written in the symbol
- connect symbols using solid lines which have arrowheads to indicate the direction
shape of symbol is not important and should be changed
false
size can be changed as required
true
symbol should not immediately recognized
false
the details inside the symbol must be clearly legible
true
types of flowchart symbol
- terminal symbol
- input/output symbol
- process symbol
- decision symbol
each flowchart has a unique start and end point.
terminal symbol
