In the following week,
we learned about Flowchart. Flowchart is a
graphical representation of an algorithm. Programmers often use it as program-planing
tool to solve a problem. it makes use of symbols which are connected among them
to indicate the flow of information and processing.
This are some basic symbol used
in flowchart design :
1. Terminal: The oval symbol indicates Start, Stop
and Halt in a program’s logic flow. A pause/halt is generally used in a program
logic under some error conditions. Terminal is the first and last symbols in
the flowchart.
2. Input/Output: A parallelogram denotes any function
of input/output type. Program instructions that take input from input devices
and display output on output devices are indicated with parallelogram in a
flowchart.
3. Processing: A box represents arithmetic
instructions. All arithmetic processes such as adding, subtracting,
multiplication and division are indicated by action or process symbol.
4. Decision Diamond symbol represents a decision
point. Decision based operations such as yes/no question or true/false are
indicated by diamond in flowchart.
5. Flow lines: Flow lines indicate the exact sequence
in which instructions are executed. Arrows represent the direction of flow of
control and relationship among different symbols of flowchart.
For Example like this :
