Algorithm and Flowchart :

In order to write computer programming without any logical error, it is recommended programmers prepare a rough writing showing the steps involved in the program. This is called an algorithm. An algorithm presents step-by-step instruction required to solve any problem. These steps can be shown diagrammatical using a flowchart.

Flowchart is a symbolic or diagrammatic representation of an algorithm. It uses several geometrical figures to represent the operations and arrows to show the direction of flow.

Programmers often use it as a program-planning tool to solve a problem. It makes use of symbols which are connected among them to indicate the flow of information and processing.

Flowchart are very helpful in writing program and explaining program to others.

Commonly used Symbols in Flowcharts :

Start / Stop (Terminal) :

Start / Stop (Terminal) : Represents the beginning and the end of the flowchart.

Input / Output :

Input/Output : Represents the values to be given by the user and the results to be displayed.

Processing :

Processing : Represents the arithmetic operation to compute a value.

Checking / Decision making :

Checking / Decision making : Represents the logical checking to decide the flow sequence.

Looping :

Looping : Represents the looping which is repeated based on a condition / value of a variable.

Connector :

Connector : Represents the Continuity of the flowchart in another place / page.

Arrows :

Arrows : Represents direction of flow.

Examples of flowcharts in programming :

Example 1:

Draw a flowchart to add two numbers entered by user :

Example 2:

Draw flowchart to find the largest among three different numbers entered by user :

Example 3:

Draw a flowchart to find all the roots of a quadratic equation ax2+bx+c=0 :

Example 4:

Draw a flowchart to find the Fibonacci series till termâ‰¤1000 :
