When we want to write a program it is firstly required to develop a working logic of the program that is to be written. Algorithm helps us to do this. It is a sequence of instruction to carry out in order to solve a program it is step by step continuing of any working logic.

Steps:-

<!--[if !supportLists]-->1. <!--[endif]-->Start

<!--[if !supportLists]-->2. <!--[endif]-->Input

<!--[if !supportLists]-->3. <!--[endif]-->Processing

<!--[if !supportLists]-->4. <!--[endif]-->Output

<!--[if !supportLists]-->5. <!--[endif]-->Stop

E.g.

<!--[if !supportLists]-->1. <!--[endif]-->Start

<!--[if !supportLists]-->2. <!--[endif]-->Let a=10, b=20

<!--[if !supportLists]-->3. <!--[endif]-->c=a+b

<!--[if !supportLists]-->4. <!--[endif]-->Print c

<!--[if !supportLists]-->5. <!--[endif]-->Stop

Merits/Advantages of Algorithm

<!--[if !supportLists]-->1. <!--[endif]-->It makes the program easy to read and understand.

<!--[if !supportLists]-->2. <!--[endif]-->It makes the program portable and efficient.

<!--[if !supportLists]-->3. <!--[endif]-->It displays easy steps of processing.

<!--[if !supportLists]-->4. <!--[endif]-->It simplifies the modification and to update of the existing program.

<!--[if !supportLists]-->5. <!--[endif]-->It provides the facility for testing a program at developing stage.
