Algorithm

Author: Ravi Poswal

A set of sequential steps usually written in Ordinary Language to solve a given problem is called Algorithm.

Steps involved in algorithm development

Step1. Identification of input

Step2: Identification of output

Step3: Identification the processing operations

Step4: Processing Definiteness

Step5 : Processing Finiteness

Step6 : Possessing Effectiveness

Code Example

Example:  1. Suppose we want to find the average of three numbers, the algorithm is as follows

Step 1 Read the numbers a, b, c

Step 2 Compute the sum of a, b and c

Step 3 Divide the sum by 3

Step 4 Store the result in variable d

Step 5 Print the value of d

Step 6 End of the program

Code Example

2. Write an algorithm to find the largest of three numbers X, Y,Z. 

Step 1: Read the numbers X,Y,Z.
Step 2: if (X > Y)
	Big = X
	else BIG = Y
Step 3 : if (BIG < Z) 
Step 4: Big = Z
Step 5: Print the largest number i.e. Big
Step 6: Stop.
