Example

Example : 1

An algorithm to find the radius of a circle, given the circumference.

Step 1	:	Input C	[ input circumference of the circle ]
Step 2	:	radius ← C / (2 * PI )	[ compute radius of the circle]
Step 3	:	Output radius	[ display output]
Step 4	:	Stop

Example 2 :

An algorithm to find the area of a rectangle

Step 1	:	Input L	[input the length of the rectangle]
Step 2	:	Input B	[input the breadth of a rectangle]
Step 3	:	Area ← L * B	[ compute the area of a rectangle ]
Step 4	:	Output Area	[Display the area]
Step 5	:	Stop

Example 3:

Algorithm to find the total and average of the marks in 5 subjects when register number, name and marks in 5 subjects are input.

Step 1	:	Initialise Total and avg to 0.
Step 2	:	Input Regno	[input Register number of student]
Step 3	:	Input Name	[input Name of the student ]
Step 4	:	Input Eng	[Input marks in English – subject 1]
Step 5	:	Input Hindi	[Input marks in Hindi – subject 2]
Step 6	:	Input Phy	[Input marks in Physics – subject 3]
Step7	:	Input Chem	[Input marks in Chemistry – subject 4]
Step 8	:	Input Stat	[Input marks in Statistics – subject 5]
Step 9	:	Total ← Eng + Hindi + Phy + Chem + Stat	[ Compute the total of all subjects ]
Step 10	:	Avg ← Tot / 5	[compute average marks]
Step 11	:	Output Total	[display total]
Step 12	:	Output Avg	[display average]
Step 13	:	stop

Example 4 :

Algorithm to find whether a number input is positive , negative or zero.

Step 1 : Input N [ input a number n]

Step 2 : Check whether N is greater than zero, if yes output N is ‘positive’, goto step 5.

Step 3 : Check whether N is less than zero, if yes output N is ‘negative’, goto step 5.

Step 4 : Output N is ‘zero’

Step 5 : Stop

Example 5 :

Algorithm to find the largest of 2 numbers.

Step 1 : Input M, N [input 2 numbers M and N]

Step 2 : Is M greater than N, if yes output M “ is larger of ” N goto Step 4.

Step 3 : Output N “is larger than ” M

Step 4 : Stop.
