Flowchart and Algorithm

Algorithm

The step-by-step process of solving any problem is known as
algorithm. The algorithm represents logic of any program. It is free
from computer languages.

Characteristics of algorithm

The features of algorithm are :

1. Input
2. Output
3. Defeniteness
4. Effectiveness
5. Finiteness

Flowchart

It 
is the symbolic representation of any algorithm(logic). We use the
following symbols in the flowchart :

Symbol	Name	Purpose
	oval	start/stop
	parallelogram	input/output
	rectangle	process
	diamond	decision making
	flow lines	direction
	connectors	connection

Illustration
of flowchart and algorithm with the help of an example : Read a number
having two digits and prints the summation of two digits.
