In this article algorithm examples we give the algorithm simple examples also conditional and lopping related examples like addition of two numbers, area of circle etc.

#### Algorithm Examples:

1. Write an algorithm to find addition of two numbers entered by the user

Step 1: Start

Step 2: Declare variables say n1, n2 and sum.

Step 3: Read values n1 and n2.

Step 4: Perform the addition of n1 and n2 and assign the result to sum.

Step 5: Display sum

Step 6: Stop

Step 1: Start

Step 2: Declare variables say length, breadth and area.

Step 4: Multiply length and breadth and assign the result to area.

Step 5: Display area

Step 6: Stop

1. Write an algorithm to find area of circle. (Area of circle=PI*r*r)

Step 1: Start

Step 2: Declare variables say radios and area.

Step 4: Multiply 3.142 into radios into radios and assign the result to area.

Step 5: Display area

Step 6: Stop

#### Algorithm Examples:

1. Write an algorithm to find Simple interest. [Simple Interest= (p*n*r)/100]

Step 1: Start

Step 2: Declare variables say p, n, r and SI.

Step 3: Read values p, n and r.

Step 4: Multiply by p into n into r and divided by 100 and assign the result to SI.
